CVE-2025-13158
CVE-2025-13158 is a CWE-1321 vulnerability. O3 Security confirms whether CVE-2025-13158 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
Prototype pollution vulnerability in apidoc-core versions 0.2.0 and all subsequent versions allows remote attackers to modify JavaScript object prototypes via malformed data structures, including the “define” property processed by the application, potentially leading to denial of service or unintended behavior in applications relying on the integrity of prototype chains. This affects the preProcess() function in api_group.js, api_param_title.js, api_use.js, and api_permission.js worker modules.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2025-13158 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 O3 protects you
O3 pinpoints whether CVE-2025-13158 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2025-13158. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2025-13158 in your dependencies?
O3 detects CVE-2025-13158 across dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
