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-2023-40000 exists.\n\nAffected product: LiteSpeed 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-2023-40000/ (Markdown: https://insights.sbomify.com/CVE-2023-40000/index.md)","id":"CVE-2023-40000","markdown":"https://insights.sbomify.com/CVE-2023-40000/index.md","name":"CVE-2023-40000","record":{"aliases":["GHSA-fvp6-8p9w-vffq"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can inject malicious scripts into WordPress sites via the LiteSpeed Cache plugin, potentially compromising user sessions and site integrity.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[{"product":"litespeed_cache","vendor":"litespeedtech"}],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in LiteSpeed Technologies LiteSpeed Cache allows Stored XSS.This issue affects LiteSpeed Cache: from n/a through 5.7.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2024-02-28","github_poc":3,"max_poc_stars":7,"metasploit":0,"nuclei":1,"refs":[{"date":"2024-02-28T19:36:40Z","kind":"github_poc","ref":"https://github.com/rxerium/CVE-2023-40000","stars":7,"title":"LiteSpeed Cache plugin for WordPress that could enable unauthenticated users to escalate their privileges"},{"date":"2024-05-12T06:13:47Z","kind":"github_poc","ref":"https://github.com/quantiom/litespeed-cache-xss-poc","stars":5,"title":"PoC for XSS vulnerability in the LiteSpeed Cache WordPress plugin (CVE-2023-40000) allowing elevated privileges.
