CVE-2026-9308 1 Mozilla 2 Firefox, Firefox For Ios 2026-06-03 5.4 Medium
Firefox for iOS Reader View replaced page content in its HTML template before replacing other internal placeholders. A malicious page could include a placeholder string that was later substituted with JSON-LD data, potentially resulting in arbitrary JavaScript execution.

CVE-2026-9309 1 Mozilla 2 Firefox, Firefox For Ios 2026-06-03 5.4 Medium
Firefox for iOS Reader View did not properly escape HTML tags in JSON-LD metadata. A malicious page could inject markup that changed Reader View behavior and leaked sensitive URL parameters. These parameters could then be used to access internal pages, potentially resulting in arbitrary JavaScript execution in an internal origin. This vulnerability was fixed in Firefox for iOS 151.2.
CVE-2026-9078 1 Mozilla 2 Firefox, Firefox For Ios 2026-05-28 5.4 Medium
Firefox for iOS displayed specially crafted right-to-left (RTL) and internationalized domain names (IDNs) incorrectly in link preview UI surfaces. A crafted RTL hostname could visually reorder portions of the displayed domain, causing attacker-controlled sites to appear as trusted origins. This vulnerability was fixed in Firefox for iOS 151.1.

CVE-2026-6785 1 Mozilla 2 Firefox, Thunderbird 2026-05-27 7.5 High
Memory safety bugs present in Firefox ESR 115.34, Firefox ESR 140.9, Thunderbird ESR 140.9, Firefox 149 and Thunderbird 149. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability was fixed in Firefox 150, Firefox ESR 115.35, Firefox ESR 140.10, Thunderbird 150, and Thunderbird 140.10.
CVE-2015-4000 13 Apple, Canonical, Debian and 10 more 31 Iphone Os, Mac Os X, Safari and 28 more 2026-05-27 3.7 Low
The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.
CVE-2026-6783 1 Mozilla 2 Firefox, Thunderbird 2026-05-27 5.3 Medium

CVE-2013-2566 4 Canonical, Fujitsu, Mozilla and 1 more 24 Ubuntu Linux, M10-1, M10-1 Firmware and 21 more 2026-05-22 5.9 Medium
The RC4 algorithm, as used in the TLS protocol and SSL protocol, has many single-byte biases, which makes it easier for remote attackers to conduct plaintext-recovery attacks via statistical analysis of ciphertext in a large number of sessions that use the same plaintext.
