EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.9 under NVD CVSS v3. EPSS exploit probability: 0.5%, top 63% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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.
