How severe is GHSA-x2fr-v8wf-8wwv?

GHSA-x2fr-v8wf-8wwv has a CVSS score of 7.7/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by GHSA-x2fr-v8wf-8wwv?

GHSA-x2fr-v8wf-8wwv affects the following packages: ruby-saml (RubyGems). Ecosystems affected: RubyGems.

How do I fix GHSA-x2fr-v8wf-8wwv?

Update ruby-saml to 1.7.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-x2fr-v8wf-8wwv is resolved across your whole dependency graph.

How do I detect GHSA-x2fr-v8wf-8wwv in my RubyGems dependencies?

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

How do I mitigate GHSA-x2fr-v8wf-8wwv 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 GHSA-x2fr-v8wf-8wwv?

O3 pinpoints whether GHSA-x2fr-v8wf-8wwv is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-x2fr-v8wf-8wwv actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-x2fr-v8wf-8wwv, 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 type of vulnerability is GHSA-x2fr-v8wf-8wwv?

GHSA-x2fr-v8wf-8wwv is classified as Improper Authentication (CWE-287). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-x2fr-v8wf-8wwv published, and has it been updated?

GHSA-x2fr-v8wf-8wwv was published on July 5, 2019 and was last updated on November 8, 2023. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

OneLogin Ruby-SAML 1.6.0 and earlier may incorrectly utilize the results of XML DOM traversal and canonicalization APIs in such a way that an attacker may be able to manipulate the SAML data without invalidating the cryptographic signature, allowing the attack to potentially bypass authentication to SAML service providers.
