CVE-2026-46359

phpMyFAQ has SQL Injection in CurrentUser::setTokenData through unescaped OAuth token fields

An attacker who can authenticate via Azure AD with a crafted claim achieves arbitrary SQL execution on the phpMyFAQ database. This permits reading all FAQ data (including restricted entries), modifying or deleting content, and extracting password hashes and session tokens of all users including administrators.

CWE: CWE-89 (SQL Injection)

Untrusted input alters a database query, allowing the attacker to read or modify data the query was not intended to access. Typical impact: data disclosure or modification.

CVE-2026-46359 has a CVSS score of 7.5 (High). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (4.1.2); upgrading removes the vulnerable code path.

1. What is CVE-2026-46359? CVE-2026-46359 is a high-severity SQL injection vulnerability in thorsten/phpmyfaq (composer), affecting versions <= 4.1.1. It is fixed in 4.1.2. Untrusted input alters a database query, allowing the attacker to read or modify data the query was not intended to access.
2. How severe is CVE-2026-46359? CVE-2026-46359 has a CVSS score of 7.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which packages are affected by CVE-2026-46359?
   • thorsten/phpmyfaq (composer) (versions <= 4.1.1)
   • phpmyfaq/phpmyfaq (composer) (versions <= 4.1.1)
4. Is there a fix for CVE-2026-46359? Yes. CVE-2026-46359 is fixed in 4.1.2. Upgrade to this version or later.
5. Is CVE-2026-46359 exploitable, and should I be worried? Whether CVE-2026-46359 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2026-46359 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2026-46359?
   • Upgrade thorsten/phpmyfaq to 4.1.2 or later
   • Upgrade phpmyfaq/phpmyfaq to 4.1.2 or later
