The Firefox and Firefox Focus UI for the Android custom tab feature only showed the "site" that was loaded, not the full hostname. User supplied content hosted on a subdomain of a site could have been used to fool a user into thinking it was content from a different subdomain of that site. This vulnerability affects Firefox < 144.
CVE-2025-11721 1 Mozilla 2 Firefox, Thunderbird 2025-10-15 9.8 Critical

CVE-2023-0163 1 Mozilla 1 Convict 2025-10-15 8.4 High
Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') vulnerability in Mozilla Convict. This allows an attacker to inject attributes that are used in other components, or to override existing attributes with ones that have incompatible type, which may lead to a crash. The main use case of Convict is for handling server-side configurations written by the admins owning the servers, and not random users. So it's unlikely that an admin would deliberately sabotage their own server. Still, a situation can happen where an admin not knowledgeable about JavaScript could be tricked by an attacker into writing the malicious JavaScript code into some config files. This issue affects Convict: before 6.2.4.
CVE-2023-1521 1 Mozilla 1 Sccache 2025-10-15 7.8 High
On Linux the sccache client can execute arbitrary code with the privileges of a local sccache server, by preloading the code in a shared library passed to LD_PRELOAD. If the server is run as root (which is the default when installing the snap package https://snapcraft.io/sccache ), this means a user running the sccache client can get root privileges.
