Which packages are affected by CVE-2010-1619?

CVE-2010-1619 affects the following packages: moodle/moodle (Packagist), moodle/moodle (Packagist). Ecosystems affected: Packagist.

How do I fix CVE-2010-1619?

Update moodle/moodle to 1.8.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2010-1619 is resolved across your whole dependency graph.

How do I detect CVE-2010-1619 in my Packagist dependencies?

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

How do I mitigate CVE-2010-1619 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-2010-1619?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2010-1619 can be triaged on real exposure rather than presence alone.

Is CVE-2010-1619 actively exploited in the wild?

No public exploit code has been indexed for CVE-2010-1619 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2010-1619?

CVE-2010-1619 has an EPSS (Exploit Prediction Scoring System) score of 1.7%, placing it in the 75th 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 indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2010-1619?

CVE-2010-1619 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-2010-1619 published, and has it been updated?

CVE-2010-1619 was published on May 13, 2022 and was last updated on April 11, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
