## What is CVE-2026-15154?

CVE-2026-15154 is a medium-severity denial of service vulnerability in Red Hat OpenShift AI 2.25, published on 8 Jul 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

A flaw was found in `guardrails-detectors`, a component of Red Hat OpenShift AI. This vulnerability, known as Regular Expression Denial of Service (ReDoS), allows a remote attacker to provide specially crafted regular expressions to the public detection API. This can cause catastrophic backtracking, leading to a worker process consuming 100% CPU indefinitely and resulting in a denial of service for the entire guardrails-mediated LLM pipeline.

Weakness: CWE-1333 (Inefficient Regular Expression Complexity)

Check this codebase for CVE-2026-15154 and fix it if it is affected.

What it is: CVE-2026-15154 is a medium-severity denial of service vulnerability in Red Hat OpenShift AI 2.25, published on 8 Jul 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-15154 in the wild and no public exploit code.

Affected product: Red Hat OpenShift AI 2.25. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
