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-2025-50891 in the wild and no public exploit code.\n\nAffected product: Adform server-side backend for Site Tracking. 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-2025-50891/ (Markdown: https://insights.sbomify.com/CVE-2025-50891/index.md)","id":"CVE-2025-50891","markdown":"https://insights.sbomify.com/CVE-2025-50891/index.md","name":"CVE-2025-50891","record":{"aliases":["GHSA-87jv-7r2h-c6wf"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Adform Site Tracking","requires_auth":"none","summary":"Attackers can inject HTML or execute arbitrary code via cookie hijacking in the Adform Site Tracking server-side backend.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"},{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The server-side backend for Adform Site Tracking before 2025-08-28 allows attackers to inject HTML or execute arbitrary code via cookie hijacking.
