What it is: CVE-2025-43738 is a medium-severity cross-site scripting vulnerability in Liferay Digital Experience Platform, published on 19 Aug 2025. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link. Exploitation: There is no known exploitation of CVE-2025-43738 in the wild and no public exploit code. Affected packages and fixed versions: - com.liferay:com.liferay.expando.web (Maven): affected all versions up to 5.0.59; no fix listed - com.liferay:com.liferay.expando.web (Maven): affected all versions up to 5.0.59; no fix listed 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.
