An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-18051 exists.\n\nAffected product: Unknown W3 Total Cache. 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-2026-18051/ (Markdown: https://insights.sbomify.com/CVE-2026-18051/index.md)","id":"CVE-2026-18051","markdown":"https://insights.sbomify.com/CVE-2026-18051/index.md","name":"CVE-2026-18051","record":{"aliases":["GHSA-3qrw-968g-4hqv"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can write arbitrary files to any directory or overwrite .htaccess files, potentially breaking the site or removing security rules.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":10,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"The W3 Total Cache WordPress plugin before 2.10.5 does not properly validate the request path it uses to build cache file names, allowing unauthenticated attackers to write a file into any existing directory on the server, inside or outside the web root, overwriting whatever occupies the target name.\nOn Apache, the same flaw overwrites the site's .htaccess files, which breaks the site and can strip hardening rules that other security measures rely on.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2026/CVE-2026-18051.yaml","stars":null,"title":"W3 Total Cache \u003c 2.10.5 - Unauthenticated Arbitrary Directory File Write"}],"tier":"weaponised"},"has_fix":null,"headline":"Path traversal in W3 Total Cache","id":"CVE-2026-18051","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"ManageWP Worker \u003c 4.9.37 - Unauthenticated Authentication Bypass via Unsigned Auto-Login Parameters","id":"CVE-2026-18052"},"packages":[],"prev":{"headline":"Events Manager \u003c 7.4 - Unauthenticated Pending Upload Disclosure via events-manager/v1/uploads","id":"CVE-2026-18050"},"products":["W3 Total Cache"],"published":"2026-08-19","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-19","vendors":["Unknown"]},"summary":"Unauthenticated attackers can write arbitrary files to any directory or overwrite .htaccess files, potentially breaking the site or removing security rules.","url":"https://insights.sbomify.com/CVE-2026-18051/"}
