Which packages are affected by CVE-2011-4969?

CVE-2011-4969 affects the following packages: jquery (Debian:10). Ecosystems affected: Debian:10.

How do I fix CVE-2011-4969?

Update jquery to 1.6.4-1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2011-4969 is resolved across your whole dependency graph.

How do I detect CVE-2011-4969 in my Debian:10 dependencies?

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

How do I mitigate CVE-2011-4969 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-2011-4969?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2011-4969 can be triaged on real exposure rather than presence alone.

Is CVE-2011-4969 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2011-4969, including 1 in-the-wild exploitation 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-2011-4969?

CVE-2011-4969 has an EPSS (Exploit Prediction Scoring System) score of 19.2%, placing it in the 97th 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-2011-4969?

CVE-2011-4969 is classified as Cross-site Scripting (XSS) (CWE-79). 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-2011-4969 published, and has it been updated?

CVE-2011-4969 was published on March 8, 2013 and was last updated on June 4, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
