Which packages are affected by GHSA-7726-43hg-m23v?

GHSA-7726-43hg-m23v affects the following packages: org.openidentityplatform.openam:openam-oauth2 (Maven). Ecosystems affected: Maven.

How do I fix GHSA-7726-43hg-m23v?

Update org.openidentityplatform.openam:openam-oauth2 to 15.0.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7726-43hg-m23v is resolved across your whole dependency graph.

How do I detect GHSA-7726-43hg-m23v in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.openidentityplatform.openam:openam-oauth2. 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-7726-43hg-m23v 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-7726-43hg-m23v?

O3 pinpoints whether GHSA-7726-43hg-m23v 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-7726-43hg-m23v actively exploited in the wild?

No public exploit code has been indexed for GHSA-7726-43hg-m23v 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 GHSA-7726-43hg-m23v?

GHSA-7726-43hg-m23v has an EPSS (Exploit Prediction Scoring System) score of 3.5%, placing it in the 88th 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 GHSA-7726-43hg-m23v?

GHSA-7726-43hg-m23v is classified as Code Injection (CWE-94). 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.

Is there exploit tooling available for GHSA-7726-43hg-m23v?

A Nuclei detection template exists for GHSA-7726-43hg-m23v, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was GHSA-7726-43hg-m23v published, and has it been updated?

GHSA-7726-43hg-m23v was published on July 25, 2024 and was last updated on July 25, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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

Description

OpenAM is an open access management solution. In versions 15.0.3 and prior, the getCustomLoginUrlTemplate method in RealmOAuth2ProviderSettings.java is vulnerable to template injection due to its usage of user input. Although the developer intended to implement a custom URL for handling login to override the default PingOne Advanced Identity Cloud login page,they did not restrict the CustomLoginUrlTemplate, allowing it to be set freely. Commit fcb8432aa77d5b2e147624fe954cb150c568e0b8 introduces TemplateClassResolver.SAFER_RESOLVER to disable the resolution of commonly exploited classes in FreeMarker template injection. As of time of publication, this fix is expected to be part of version 15.0.4.
