Summary
firefox vulnerabilities
Details

Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. (CVE-2025-1933, CVE-2025-1934, CVE-2025-1935, CVE-2025-1936, CVE-2025-1937, CVE-2025-1942)

It was discovered that Firefox did not properly handle WebTransport connection, leading to a use-after-free vulnerability. An attacker could potentially exploit this issue to cause a denial of service. (CVE-2025-1931)

Ivan Fratric discovered that Firefox did not properly handle XSLT sorting, leading to a out-of-bounds access vulnerability. An attacker could potentially exploit this issue to cause a denial of service, or execute arbitrary code. (CVE-2025-1932)
