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-2026-91942 exists.\n\nAffected product: unclecode crawl4ai. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-91942/ (Markdown: https://insights.sbomify.com/CVE-2026-91942/index.md)","id":"CVE-2026-91942","markdown":"https://insights.sbomify.com/CVE-2026-91942/index.md","name":"CVE-2026-91942","record":{"aliases":["GHSA-7g3g-vhm6-79f3","GHSA-xjmx-xxmr-qf54"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Web crawling library","requires_auth":"none","summary":"Attackers can execute JavaScript in the Docker Playground UI via malicious PDFs to steal API tokens and abuse authenticated APIs.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"crawl4ai before 0.9.3 contains a DOM-based cross-site scripting vulnerability in the Docker Playground UI that assigns untrusted crawl results to element.innerHTML.
