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

Description

Auth0 angular-jwt before 0.1.10 treats whiteListedDomains entries as regular expressions, which allows remote attackers with knowledge of the jwtInterceptorProvider.whiteListedDomains setting to bypass the domain allowlist filter via a crafted domain.

For example, if the setting is initialized with:

jwtInterceptorProvider.whiteListedDomains = ['whitelisted.Example.com'];

An attacker can set up a domain whitelistedXexample.com that will pass the allow list filter, as it considers the . separator to be a regex whildcard which matches any character.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for angular-jwt. 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.

  2. Fix

    Update angular-jwt to 0.1.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vm2p-f5j4-mj6g is resolved across your whole dependency graph.

  3. Workarounds

    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 pinpoints whether GHSA-vm2p-f5j4-mj6g 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 GHSA-vm2p-f5j4-mj6g. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

Frequently Asked Questions

Auth0 angular-jwt before 0.1.10 treats whiteListedDomains entries as regular expressions, which allows remote attackers with knowledge of the `jwtInterceptorProvider.whiteListedDomains` setting to bypass the domain allowlist filter via a crafted domain. For example, if the setting is initialized with: `jwtInterceptorProvider.whiteListedDomains = ['whitelisted.Example.com'];` An attacker can set up a domain `whitelistedXexample.com` that will pass the allow list filter, as it considers the `.` separator to be a regex whildcard which matches any character.
