Detailsinfo

A vulnerability has been found in ttop32 MouseTooltipTranslator up to 0.1.127 and classified as critical. Affected by this vulnerability is an unknown part of the file viewer.html of the component URL Parameter Handler. The manipulation with an unknown input leads to a server-side request forgery vulnerability. The CWE definition for the vulnerability is CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.
