🚨 CVE-2026-42390
An invalid zone might pass ZONEMD validation while it should not. This is only relevant if ZoneToCache is configured with ZONEMD validation.

🚨 CVE-2026-13222
Our payment integration with Oppwa-based payment methods did not
properly validate payment status responses. An attacker could use a
successful payment status response from one payment and supply it to the
system for a different payment, gaining access to multiple valid
tickets with only one payment.

🚨 CVE-2026-13223
Our payment integration with Computop-based payment methods did not
properly validate payment status responses. An attacker could use a
successful payment status response from one payment and supply it to the
system for a different payment, gaining access to multiple valid
tickets with only one payment.

🚨 CVE-2026-46735
Dell Display and Peripheral Manager (DDPM Mac), versions prior to 2.3, contain an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Command execution.

🚨 CVE-2026-49319
Remote Keyless Entry System (RKES), using the 433 MHz key fob bearing FCC ID CWTR53R0 manufactured by ALPS ALPINE CO., LTD., is vulnerable to a roll-back attack against its rolling-code authentication. 



An attacker within RF range who records two consecutive lock or unlock transmissions from a legitimate key fob can later replay the same pair of transmissions repeatedly. During testing, replaying the first captured transmission caused the RKES to enter a state in which replaying the second captured transmission resulted in a successful lock or unlock operation of the vehicle. Tested and confirmed on a 2024 Suzuki Swift (SWIFT ISG GLS AC 1.2 5P 4x2 TM).

🚨 CVE-2026-57234
Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, the NONET parse option, which Nokogiri turns on by default for Nokogiri::XML::Schema (see CVE-2020-26247), was not correctly enforced on the JRuby implementation. As a result, a schema parsed with default options could still cause external resources to be fetched over the network, potentially enabling SSRF or XXE attacks. This vulnerability is fixed in 1.19.4.

🚨 CVE-2026-57235
Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, Nokogiri::XML::NodeSet#[] (and its alias #slice) checked the requested index against the node set's bounds using a 32-bit-truncated copy of the index. A large negative index could pass the check and then be used at full width, reading outside the node set's storage. On CRuby this is an out-of-bounds read that typically crashes the process; on JRuby it is not memory-unsafe but returns an incorrect node. This vulnerability is fixed in 1.19.4.

🚨 CVE-2026-57236
Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, calling Document#encoding= with an invalid encoding (e.g., a non-string, or a string containing a null byte) raises an exception, but only after freeing the document's current encoding string without replacing it. The document is left referencing freed memory, so the next call to Document#encoding reads invalid memory, which can cause a segfault or leak freed bytes into a Ruby String. Affects the CRuby (libxml2) implementation only; JRuby is not affected. This vulnerability is fixed in 1.19.4.
