An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-45801 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- dompurify (npm): affected all versions; fixed in 2.5.4\n- dompurify (npm): affected all versions; fixed in 2.5.4\n- dompurify (npm): affected from 3.0.0; fixed in 3.1.3\n- dompurify (npm): affected from 3.0.0; fixed in 3.1.3\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-2024-45801/ (Markdown: https://insights.sbomify.com/CVE-2024-45801/index.md)","id":"CVE-2024-45801","markdown":"https://insights.sbomify.com/CVE-2024-45801/index.md","name":"CVE-2024-45801","record":{"aliases":["DEBIAN-CVE-2024-45801","GHSA-mmhx-hmjr-r674","MINI-q7cx-7c9m-56pp","UBUNTU-CVE-2024-45801"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript XSS sanitizer","requires_auth":"none","summary":"Attackers can bypass DOMPurify's depth checks via prototype pollution to execute cross-site scripting attacks, requiring users to upgrade the library.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"dompurify","vendor":"cure53"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"},{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"DOMPurify is a DOM-only, super-fast, uber-tolerant XSS sanitizer for HTML, MathML and SVG. It has been discovered that malicious HTML using special nesting techniques can bypass the depth checking added to DOMPurify in recent releases. It was also possible to use Prototype Pollution to weaken the depth check. This renders dompurify unable to avoid cross site scripting (XSS) attacks. This issue has been addressed in versions 2.5.4 and 3.1.3 of DOMPurify. All users are advised to upgrade.
