What it is: CVE-2025-43746 is a medium-severity cross-site scripting vulnerability in Liferay Digital Experience Platform, published on 20 Aug 2025. An attacker needs administrator access to exploit it, with no action from the victim. Exploitation: There is no known exploitation of CVE-2025-43746 in the wild and no public exploit code. Affected packages and fixed versions: - ccom.liferay:com.liferay.dynamic.data.mapping.web (Maven): affected all versions; fixed in 5.0.122 - ccom.liferay:com.liferay.dynamic.data.mapping.web (Maven): affected all versions; fixed in 5.0.122 - com.liferay.portal:release.portal.bom (Maven): affected from 7.4.0-ga1 up to 7.4.3.132-ga132; no fix listed - com.liferay.portal:release.portal.bom (Maven): affected from 7.4.0-ga1 up to 7.4.3.132-ga132; 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.
