CVE-2026-75140 is a high-severity denial of service vulnerability in jhy soup, published on 20 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description jsoup through 1.23.2, fixed in commit 862ba2f, contains an uncontrolled resource consumption vulnerability in XmlTreeBuilder that allows remote attackers to exhaust JVM heap memory by supplying a deeply nested XML document with uniquely-namespaced elements. The builder copies the entire inherited namespace map on every start element, causing quadratic time and memory complexity, which attackers can exploit to trigger an OutOfMemoryError and terminate the application.

What it is: CVE-2026-75140 is a high-severity denial of service vulnerability in jhy soup, published on 20 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim. Exploitation: There is no known exploitation of CVE-2026-75140 in the wild and no public exploit code. Affected packages and fixed versions: - org.jsoup:jsoup (Maven): affected all versions; fixed in 1.23.2 - org.jsoup:jsoup (Maven): affected all versions; fixed in 1.23.2 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.
