Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-1781 exists.\n\nAffected product: W3C CSS Validator. 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-2025-1781/ (Markdown: https://insights.sbomify.com/CVE-2025-1781/index.md)","id":"CVE-2025-1781","markdown":"https://insights.sbomify.com/CVE-2025-1781/index.md","name":"CVE-2025-1781","record":{"aliases":[],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"W3C CSS Validator","requires_auth":"low_privilege","summary":"An attacker can exploit an XML External Entity vulnerability in the W3C CSS Validator to perform SSRF and read arbitrary local files.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Google","cpe":[{"product":"css_validator","vendor":"w3"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:L/SC:N/SI:H/SA:L","version":"4.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"There is a XXE in W3CSS Validator versions before cssval-20250226 that allows an attacker to use specially-crafted XML objects to coerce server-side request forgery (SSRF).  This could be exploited to read arbitrary local files if an attacker has access to exception messages.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"XML external entity in CSS Validator","id":"CVE-2025-1781","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xxe","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Unsanitized input in language form field","id":"CVE-2025-1782"},"packages":[],"prev":{"headline":"Missing authorization in BuddyPress WooCommerce My Account Integration.
