Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-23891 in the wild and no public exploit code.\n\nAffected product: Vincent Loy Yet Another Countdown. 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-2025-23891/ (Markdown: https://insights.sbomify.com/CVE-2025-23891/index.md)","id":"CVE-2025-23891","markdown":"https://insights.sbomify.com/CVE-2025-23891/index.md","name":"CVE-2025-23891","record":{"aliases":["GHSA-9xh9-h96r-f8m8"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"An attacker can inject malicious scripts via DOM-based XSS in the Yet Another Countdown WordPress plugin, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/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 Vincent Loy Yet Another Countdown yacp allows DOM-Based XSS.This issue affects Yet Another Countdown: from n/a through \u003c= 1.0.1.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"WordPress Yet Another Countdown Plugin plugin \u003c= 1.0.1 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2025-23891","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"WordPress Progress Tracker plugin \u003c= 0.9.3 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2025-23892"},"packages":[],"prev":{"headline":"WordPress Easy Tweet Embed plugin \u003c= 1.7 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2025-23890"},"products":["Yet Another Countdown"],"published":"2025-01-16","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)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Vincent Loy"]},"summary":"An attacker can inject malicious scripts via DOM-based XSS in the Yet Another Countdown WordPress plugin, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2025-23891/"}
