CVE-2026-33170 Rails Active Support has a possible XSS vulnerability in SafeBuffer#%

Active Support is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, SafeBuffer% does not propagate the @htmlunsafe flag to the newly created buffer. If a SafeBuffer is mutated in place e.g. via gsub! and th...

CVE-2026-33131

CVE-2026-33131 affects H3, a minimal HTTP framework. Versions 2.0.0-0 through 2.0.1-rc.14 expose a Host header spoofing flaw in the NodeRequestUrl/FastURL path, enabling middleware bypass when an attacker manipulates event.url properties (e.g., via Host header) so route matching succeeds but auth...
