An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-28338 exists.\n\nAffected packages and fixed versions:\n- net.sourceforge.pmd:pmd-core (Maven): affected all versions; fixed in 7.22.0\n- net.sourceforge.pmd:pmd-core (Maven): affected all versions; fixed in 7.22.0\n\nTask:\n1. 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.\n2. 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.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-28338/ (Markdown: https://insights.sbomify.com/CVE-2026-28338/index.md)","id":"CVE-2026-28338","markdown":"https://insights.sbomify.com/CVE-2026-28338/index.md","name":"CVE-2026-28338","record":{"aliases":["GHSA-8rr6-2qw5-pc7r"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"PMD static analyzer","requires_auth":"none","summary":"Attackers can execute arbitrary JavaScript in browsers by crafting source code analyzed by PMD using legacy HTML report formats.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"pmd","vendor":"pmd_project"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"PMD is an extensible multilanguage static code analyzer. Prior to version 7.22.0, PMD's `vbhtml` and `yahtml` report formats insert rule violation messages into HTML output without escaping. When PMD analyzes untrusted source code containing crafted string literals, the generated HTML report contains executable JavaScript that runs when opened in a browser. Practical impact is limited because `vbhtml` and `yahtml` are legacy formats rarely used in practice. The default `html` format is properly escaped and not affected.
