{"cve":"CVE-2025-25303","nvd":{"published":"2025-03-03T17:15:15.073","modified":"2026-06-17T09:00:39.020","status":"Deferred","description":"The MouseTooltipTranslator Chrome extension allows mouseover translation of any language at once. The MouseTooltipTranslator browser extension is vulnerable to SSRF attacks. The pdf.mjs script uses the URL parameter from the current URL as the file to download and display to the extension user. Because pdf.mjs is imported in viewer.html and viewer.html is accessible to all URLs, an attacker can force the user’s browser to make a request to any arbitrary URL. After discussion with maintainer, patching this issue would require disabling a major feature of the extension in exchange for a low severity vulnerability. Decision to not patch issue.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","score":6.9},"cvss_v3":null,"cwes":["CWE-918"],"references":["https://github.com/ttop32/MouseTooltipTranslator/blob/0.1.127/public/manifest.json#L23","https://github.com/ttop32/MouseTooltipTranslator/blob/0.1.127/public/pdfjs/build/pdf.mjs#L13932","https://securitylab.github.com/advisories/GHSL-2024-018_MouseTooltipTranslator/"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2025-25303","score":0.0049,"percentile":0.42138,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
