Exploitation Status

No confirmed exploitation observed yet

  • CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
  • A successful exploit gives an attacker total control of the affected component, not partial access.
  • CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

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

Open-source dependency
  1. Detect

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

  2. Remediation status

    No patched version of apidoc-core 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.

  3. 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.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2025-13158 can be triaged on real exposure rather than presence alone.

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.
