GHSA-G623-JCGG-MHMM Users with `create` but not `override` privileges can perform local sync

Impact "Local sync" is an Argo CD feature that allows developers to temporarily override an Application's manifests with locally-defined manifests. Use of the feature should generally be limited to highly-trusted users, since it allows the user to bypass any merge protections in git. An improper...

CVE-2023-50726

A flaw was found in the Argo CD package. An improper validation bug allows users to sync local manifests on app creation, who have create privileges but not override privileges. All other restrictions, including AppProject restrictions, are still enforced. The only restriction that is not enforce...

Vulnerability of microprogramming software for Intel, AMD, ARM, and IBM processors: This vulnerability arises due to the creation of racing states in a speculative mode, which can lead to access to already freed memory areas. If the processor mispredicts the branching in the code, it allows a hacker to gain access to protected memory.

The vulnerability of microprogramming software for processors from Intel, AMD, ARM, and IBM arises from the existence of speculative execution states that can lead to access to already freed memory areas, if the processor mispredicts branch instructions in the code. Exploiting this vulnerability...
