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-2026-18855 in the wild and no public exploit code.\n\nAffected product: jackdewey Link Library. 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-2026-18855/ (Markdown: https://insights.sbomify.com/CVE-2026-18855/index.md)","id":"CVE-2026-18855","markdown":"https://insights.sbomify.com/CVE-2026-18855/index.md","name":"CVE-2026-18855","record":{"aliases":["GHSA-wm9p-2xmp-4mp2"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can delete arbitrary files, potentially leading to remote code execution, if a specific plugin option is enabled and links are deleted.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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 Link Library plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the ll_delete_link_fields function in all versions up to, and including, 7.9.4 This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).
