CVE-2026-33306

A flaw was found in bcrypt-ruby, a Ruby binding for the OpenBSD bcrypt password hashing algorithm, specifically in its JRuby implementation. When the cost parameter is set to 31, an integer overflow occurs, causing the key-strengthening loop to execute zero iterations. This significantly weakens...

CVE-2026-33176

A flaw was found in Active Support, a toolkit of support libraries for Ruby on Rails. A remote attacker can exploit this vulnerability by providing specially crafted strings containing scientific notation e.g., "1e10000" to number helpers. This input causes the BigDecimal component to expand into...

CVE-2026-33306

bcrypt-ruby is a Ruby binding for the OpenBSD bcrypt password hashing algorithm. Prior to version 3.1.22, an integer overflow in the Java BCrypt implementation for JRuby can cause zero iterations in the strengthening loop. Impacted applications must be setting the cost to 31 to see this happen. T...

SUSE CVE-2026-33210

Ruby JSON is a JSON implementation for Ruby. From version 2.14.0 to before versions 2.15.2.1, 2.17.1.2, and 2.19.2, a format string injection vulnerability can lead to denial of service attacks or information disclosure, when the allowduplicatekey: false parsing option is used to parse user...

UBUNTU-CVE-2026-33202

Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Storage's DiskServicedeleteprefixed passes blob keys directly to Dir.glob without escaping glob metacharacters. If a blob key contains attacker-controlled inp...

CVE-2026-33176

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, Active Support number helpers accept strings containing scientific notation e.g. 1e10000, which BigDecimal expands into extremely large...

UBUNTU-CVE-2026-33174

Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, when serving files through Active Storage's proxy delivery mode, the proxy controller loads the entire requested byte range into memory before sending it. A request...
