The PostgreSQL adapter in Active Record before 6.1.2.1, 6.0.3.5, 5.2.4.5 suffers from a regular expression denial of service (REDoS) vulnerability. Carefully crafted input can cause the input validation in the `money` type of the PostgreSQL adapter in Active Record to spend too much time in a regular expression, resulting in the potential for a DoS attack. This only impacts Rails applications that are using PostgreSQL along with money type columns that take user input. El adaptador PostgreSQL en Active Record versiones anteriores a 6.1.2.1, 6.0.3.5, 5.2.4.5, sufre una vulnerabilidad de denegación de servicio de expresión regular (REDoS). Una entrada cuidadosamente diseñada puede causar que la comprobación de la entrada en el tipo "money" del adaptador de PostgreSQL en Active Record pase demasiado tiempo en una expresión regular, resultando en la posibilidad de un ataque DoS. • https://github.com/halkichi0308/CVE-2021-22880 https://discuss.rubyonrails.org/t/cve-2021-22880-possible-dos-vulnerability-in-active-record-postgresql-adapter/77129 https://hackerone.com/reports/1023899 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MO5OJ3F4ZL3UXVLJO6ECANRVZBNRS2IH https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XQ3NS4IBYE2I3MVMGAHFZBZBIZGHXHT3 https://security.netapp.com/advisory/ntap-20210805-0009 https://www.debian.org/ • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2020-8165
A deserialization of untrusted data vulnernerability exists in rails < 5.2.4.3, rails < 6.0.3.1 that can allow an attacker to unmarshal user-provided objects in MemCacheStore and RedisCacheStore potentially resulting in an RCE. Se presenta una vulnerabilidad de deserialización de datos no confiables en rails versiones anteriores a 5.2.4.3, rails versiones anteriores a 6.0.3.1, que puede permitir a un atacante desarmar los objetos proporcionados por el usuario en MemCacheStore y RedisCacheStore, lo que podría generar un RCE A flaw was found in rubygem-activesupport. An untrusted user input can be written to the cache store using the `raw: true` parameter which can lead to the result being evaluated as a marshaled object instead of plain text.
