An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-72925 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @swc/html (npm): affected all versions; fixed in 1.15.47-nightly-20260729.1\n- @swc/html (npm): affected all versions; fixed in 1.15.47-nightly-20260729.1\n- swc_html_minifier (crates.io): affected all versions; fixed in 59.0.0\n- swc_html_minifier (crates.io): affected all versions; fixed in 59.0.0\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-2026-72925/ (Markdown: https://insights.sbomify.com/CVE-2026-72925/index.md)","id":"CVE-2026-72925","markdown":"https://insights.sbomify.com/CVE-2026-72925/index.md","name":"CVE-2026-72925","record":{"aliases":["GHSA-5qr2-v392-m9g8"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SWC HTML minifier","requires_auth":"none","summary":"An attacker can execute arbitrary JavaScript in the victim's browser by injecting a closing script tag into JSON data processed by the SWC HTML minifier.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"SWC is a TypeScript / JavaScript compiler written in Rust.
