What this Vulnerability Is and Why It Matters
CVE-2026-13498 is a SQL injection vulnerability affecting the GitHub project yashpokharna2555/restaurent-management-system. According to the NVD description, the vulnerable component is /forgotpassword.php, and the specific attack surface is the email POST parameter. The issue is described as remotely exploitable, which means an attacker can reach it over HTTP if the application is exposed.
For defenders, the important point is not just that this is “another SQLi,” but where it lives: the password reset path. Password reset functionality often sits at the edge of authentication workflows and is commonly reachable before login. Even when the exact backend query is unknown, SQL injection in this location can create outsized risk because it may expose user records, alter reset logic, or allow account-oriented abuse depending on how the application builds queries and what permissions the database account has.
NVD also states that a public exploit is available. That does not automatically mean mass exploitation is underway, but it materially changes defender assumptions. Once exploit details are public, opportunistic probing tends to follow quickly, especially for internet-facing PHP applications with predictable paths like /forgotpassword.php.
Affected Products and Versions
The affected product is identified as yashpokharna2555/restaurent-management-system, with the vulnerable file listed as /forgotpassword.php. The attack is tied to the email POST parameter in that component. The repository naming is important here because this appears to be a GitHub-hosted project rather than a commercial product line with formal release engineering and advisory processes.
The most important limitation is versioning. NVD explicitly states that the product does not use versioning and that affected and unaffected releases are unavailable. That means there is no trustworthy source-backed version range such as “1.2.0 through 1.4.5” and there is no confirmed fixed version number to cite. In practical terms, defenders should treat all deployed copies derived from this repository as potentially affected unless they have independently reviewed and corrected the vulnerable code path.
Because no formal versions are available, the safest language is:
- Affected versions: unknown; the project does not use versioning.
- Affected code states: any deployment containing the vulnerable
forgotpassword.phpimplementation should be treated as potentially vulnerable. - Fixed version: unknown. No upstream fixed version was identified in the available primary-source data.
If your organization forked this project, copied it into an internal application, or deployed it from a snapshot rather than a tagged release, you cannot rely on package manager metadata to scope exposure. You will need to inspect the code directly and inventory running instances by file path and application fingerprint.
Severity and Exploitation Status
The published CVSS base score is 7.3, which places this issue in the High severity range. The full vector string was not exposed in the source data used here, so it should not be invented. Likewise, while password reset routes are often unauthenticated, the primary-source record does not explicitly state the privileges requirement. Defenders should therefore assume the worst reasonable case for triage: if the reset page is reachable without login, treat this as externally exploitable without authentication until validated otherwise.
On exploitation status, the current picture is mixed but actionable. NVD says that the exploit is publicly available and might be used. That is enough to classify this issue as having a known public exploit or PoC. However, this CVE is not listed in the CISA Known Exploited Vulnerabilities catalog at the time of publication, so there is no CISA-confirmed evidence of active exploitation in the wild based on that source.
That distinction matters operationally:
| Question | Current answer |
|---|---|
| Is a public exploit or PoC known? | Yes, per NVD |
| Is exploitation in the wild confirmed by CISA KEV? | No |
| Should defenders wait for exploitation telemetry before acting? | No, because public exploit availability lowers the barrier to attack |
If you are prioritizing a backlog, this should rank above many “theoretical” flaws because exploitability is remote and public exploit availability is already noted by NVD.
What Defenders Should Do First
First, identify whether you are actually running this application or any derivative of it. Search code repositories, VM images, containers, and web roots for the repository name, the file forgotpassword.php, and any login or reset flow using that exact path. Small organizations often have one-off PHP apps deployed outside normal asset management, so this step is critical.
Second, determine exposure. If the password reset endpoint is internet-accessible, place immediate controls around it while you inspect the code. That can mean temporary IP allowlisting, HTTP authentication in front of the application, WAF rules targeting the route, or taking the reset feature offline if business impact is acceptable. Because no confirmed patch or fixed release is available, containment is part of remediation, not just a stopgap.
Third, review the backend query handling in forgotpassword.php. The remediation target is not “sanitize harder” in the generic sense; it is to remove attacker-controlled SQL construction and replace it with parameterized queries or prepared statements. Also review the database user’s privileges. Least privilege can limit blast radius if attackers find additional injection points.
Risk Framing for SMBs and IT Admins
For SMBs, the danger is less about this specific repository’s popularity and more about how these projects are commonly deployed: directly on shared hosting, VPS instances, or internal servers with minimal monitoring. A single vulnerable password reset page can expose customer records or provide a foothold for further compromise, especially if the database account has broad privileges.
For IT admins without development resources, the practical decision is straightforward. If the application is internet-facing and you cannot review or patch forgotpassword.php today, disable or restrict the endpoint. If the application is business-critical, place it behind access controls and closely monitor logs while coordinating a code fix. Because there is no confirmed vendor patch path, local ownership is required.
Bottom Line
CVE-2026-13498 is a high-severity remote SQL injection in the password reset workflow of yashpokharna2555/restaurent-management-system, specifically in /forgotpassword.php via the email POST parameter. A public exploit is reported by NVD, but there is no CISA KEV confirmation of exploitation in the wild.
There is also no trustworthy affected version range and no confirmed fixed version because the project does not use formal versioning. In the absence of an upstream patch, defenders should assume any deployed copy containing the vulnerable file is affected, restrict exposure immediately, and implement a local code fix using parameterized queries.

Detection and Hunting Guidance
Detection should focus on the route /forgotpassword.php, the email POST parameter, and typical SQL injection probe patterns. Because the exact exploit payload is not confirmed in the available primary sources, defenders should look for both noisy and low-noise attempts: quote characters, comment markers, boolean logic, UNION probes, and time-based payloads.
At the application and web server layers, look for repeated POST requests to /forgotpassword.php containing suspicious characters in the email field or unusually high request rates from a single source. On the database side, watch for SQL errors tied to the reset workflow, unexpected query latency spikes, or anomalous result sets involving user tables during reset requests.
Technical Notes
Example Apache or access log patterns to review:
POST /forgotpassword.php HTTP/1.1
email=test@example.com' OR '1'='1
email=test@example.com' UNION SELECT
email=test@example.com' AND SLEEP(5)-- -
email=' OR 1=1-- -
A quick grep on common web logs:
grep -RniE "forgotpassword\.php|UNION SELECT|SLEEP\(|OR '1'='1|-- -" /var/log/apache2 /var/log/httpd /var/log/nginx
A simple Splunk search for suspicious requests to the reset endpoint:
index=web ("forgotpassword.php" AND method=POST)
| regex _raw="(?i)(union\s+select|sleep\s*\(|or\s+['"]?1['"]?=['"]?1|--\s|/\*|benchmark\s*\()"
| stats count by src_ip, uri_path, http_user_agent
A basic Sigma-style idea for translation into your SIEM:
title: Suspicious SQLi Probing on forgotpassword.php
logsource:
category: webserver
detection:
selection:
cs-uri-stem: "/forgotpassword.php"
cs-method: "POST"
keywords:
- "UNION SELECT"
- "SLEEP("
- " OR '1'='1"
- "-- -"
- "/*"
condition: selection and keywords
level: high
If you lack detailed POST body logging, use reverse proxy telemetry, WAF logs, or HTTP request captures where legally and operationally appropriate. In the absence of body visibility, repeated 500 responses, response-time anomalies, and spikes in reset requests are still useful signals.
Mitigation and Remediation
There is currently no confirmed upstream patch and no confirmed fixed version number available from the source-backed data. That means the mitigation plan must assume you may need to patch locally. If you are relying on this project in production, waiting for an upstream release is not a defensible strategy unless you have verified compensating controls that fully prevent access to the vulnerable code path.
The durable fix is to replace dynamic SQL in forgotpassword.php with parameterized queries. Input validation for the email field is still recommended, but validation alone is not a substitute for prepared statements. You should also review error handling to avoid leaking SQL errors to clients, and reduce database privileges for the application account so the password reset code can only perform the minimum necessary operations.
Technical Notes
If the application is deployed from a Git clone, first identify whether local changes exist:
cd /var/www/html/restaurent-management-system
git status
git remote -v
If you maintain your own fork, create and deploy a local fix. Example PHP mysqli pattern using a prepared statement:
<?php
$email = $_POST['email'] ?? '';
$stmt = $conn->prepare("SELECT id, email FROM users WHERE email = ?");
$stmt->bind_param("s", $email);
$stmt->execute();
$result = $stmt->get_result();
?>
If the current file builds SQL with string concatenation, replace that logic before redeployment. Example deployment flow for a locally maintained app:
cd /var/www/html/restaurent-management-system
cp forgotpassword.php forgotpassword.php.bak.$(date +%F)
vi forgotpassword.php
php -l forgotpassword.php
systemctl reload apache2
If you cannot patch immediately, restrict access to the vulnerable route at the web server. Example Apache temporary block:
<Location "/forgotpassword.php">
Require ip 10.0.0.0/8 192.168.0.0/16
</Location>
Then apply and reload:
apachectl configtest && systemctl reload apache2
Example Nginx temporary deny rule:
location = /forgotpassword.php {
allow 10.0.0.0/8;
allow 192.168.0.0/16;
deny all;
}
Then test and reload:
nginx -t && systemctl reload nginx
If the application sits behind a WAF, add a route-specific rule to inspect the email parameter for SQL meta-characters and common injection strings. Treat WAF filtering as a compensating control, not a final fix.
