Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-4350 in the wild and no public exploit code.\n\nAffected product: Perfmatters. 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-2026-4350/ (Markdown: https://insights.sbomify.com/CVE-2026-4350/index.md)","id":"CVE-2026-4350","markdown":"https://insights.sbomify.com/CVE-2026-4350/index.md","name":"CVE-2026-4350","record":{"aliases":["GHSA-7hmf-75fm-xr24"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated subscribers can delete arbitrary files via path traversal, potentially forcing site reinstallation and takeover.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/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 Perfmatters plugin for WordPress is vulnerable to arbitrary file deletion via path traversal in all versions up to, and including, 2.5.9.1. This is due to the `PMCS::action_handler()` method processing the `$_GET['delete']` parameter without any sanitization, authorization check, or nonce verification. The unsanitized filename is concatenated with the storage directory path and passed to `unlink()`. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary files on the server by using `../` path traversal sequences, including `wp-config.php` which would force WordPress into the installation wizard and allow full site takeover.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-04-11","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-04-11T02:46:23Z","kind":"github_poc","ref":"https://github.com/whyiamsobusy/CVE-2026-4350","stars":0,"title":"CVE-2026-4350 - Perfmatters WordPress Arbitrary File Deletion"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Perfmatters \u003c= 2.5.9.1 - Authenticated (Subscriber+) Arbitrary File Deletion via 'delete' Parameter","id":"CVE-2026-4350","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Perfmatters \u003c= 2.5.9 - Authenticated (Subscriber+) Arbitrary File Overwrite via 'snippets' Parameter","id":"CVE-2026-4351"},"packages":[],"prev":{"headline":"Duende IdentityServer4 Token Renewal Endpoint authorize improper authentication","id":"CVE-2026-4349"},"products":["Perfmatters"],"published":"2026-04-03","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":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-08","vendors":["perfmatters"]},"summary":"Authenticated subscribers can delete arbitrary files via path traversal, potentially forcing site reinstallation and takeover.","url":"https://insights.sbomify.com/CVE-2026-4350/"}
