No CVSS score has been assigned to CVE-2011-2505 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2011-2505?

CVE-2011-2505 affects the following packages: phpmyadmin/phpmyadmin (Packagist), phpmyadmin/phpmyadmin (Packagist). Ecosystems affected: Packagist.

How do I fix CVE-2011-2505?

Update phpmyadmin/phpmyadmin to 3.3.10.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2011-2505 is resolved across your whole dependency graph.

How do I detect CVE-2011-2505 in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for phpmyadmin/phpmyadmin, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2011-2505 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2011-2505?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2011-2505 can be triaged on real exposure rather than presence alone.

Is CVE-2011-2505 actively exploited in the wild?

Yes. There are 4 known exploit references for CVE-2011-2505, including 2 documented proof-of-concept exploits on Exploit-DB and 2 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2011-2505?

CVE-2011-2505 has an EPSS (Exploit Prediction Scoring System) score of 12.9%, placing it in the 96th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score warrants monitoring and prompt remediation.

What type of vulnerability is CVE-2011-2505?

CVE-2011-2505 is classified as Code Injection (CWE-94). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2011-2505 published, and has it been updated?

CVE-2011-2505 was published on July 14, 2011 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

libraries/auth/swekey/swekey.auth.lib.php in the Swekey authentication feature in phpMyAdmin 3.x before 3.3.10.2 and 3.4.x before 3.4.3.1 assigns values to arbitrary parameters referenced in the query string, which allows remote attackers to modify the SESSION superglobal array via a crafted request, related to a "remote variable manipulation vulnerability."
