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 GHSA-hpr5-wp7c-hh5q in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mrk.js (npm): affected all versions; fixed in 2.0.1\n- mrk.js (npm): affected all versions; fixed in 2.0.1\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/GHSA-hpr5-wp7c-hh5q/ (Markdown: https://insights.sbomify.com/GHSA-hpr5-wp7c-hh5q/index.md)","id":"GHSA-hpr5-wp7c-hh5q","markdown":"https://insights.sbomify.com/GHSA-hpr5-wp7c-hh5q/index.md","name":"GHSA-hpr5-wp7c-hh5q","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript markdown library","requires_auth":"none","summary":"An attacker can inject malicious scripts via markdown conversion in mrk.js, potentially executing code in the victim's browser.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Versions of `mrk.js` before 2.0.1 are vulnerable to cross-site scripting (XSS) when markdown is converted to HTML.\n\n## Recommendation\n\nUpdate to version 2.0.1 or later and use `mark.sanitizeURL()` for any `src` and `href` attributes when extending the markdown.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"Cross-Site Scripting in mrk.js","id":"GHSA-hpr5-wp7c-hh5q","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2020"},"n_packages":2,"n_references":null,"packages":[{"ecosystem":"npm","fixed":["2.0.1"],"introduced":["0"],"last_affected":[],"package":"mrk.js","purl":null,"source":"GHSA-hpr5-wp7c-hh5q"},{"ecosystem":"npm","fixed":["2.0.1"],"introduced":["0"],"last_affected":[],"package":"mrk.js","purl":"pkg:npm/mrk.js","source":"GHSA-hpr5-wp7c-hh5q"}],"products":null,"published":"2020-09-01","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"An attacker can inject malicious scripts via markdown conversion in mrk.js, potentially executing code in the victim's browser.","url":"https://insights.sbomify.com/GHSA-hpr5-wp7c-hh5q/"}
