CVE-2025-52886 is a medium-severity use after free vulnerability in Freedesktop Poppler, published on 2 Jul 2025. It can only be exploited from the same machine or local network, with no action from the victim. ### Official description Poppler is a PDF rendering library. Versions prior to 25.06.0 use `std::atomic_int` for reference counting. Because `std::atomic_int` is only 32 bits, it is possible to overflow the reference count and trigger a use-after-free. Version 25.06.0 patches the issue. Weakness: CWE-416 (Use After Free) ## Which versions are affected by CVE-2025-52886?

What it is: CVE-2025-52886 is a medium-severity use after free vulnerability in Freedesktop Poppler, published on 2 Jul 2025. 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-2025-52886 in the wild and no public exploit code. Affected product: Freedesktop Poppler. 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.
