CVE-2026-72878: Improper Neutralization of Special Elements used in an OS Command

Dokploy is a free, self-hostable Platform as a Service PaaS. Prior to 0.29.13, Dokploy's backup and restore pipeline constructs shell commands by directly interpolating user-controlled database fields into bash -c "..." and sh -c "..." strings, then executes them via childprocess.exec. An...

CVE-2026-19278: Permissive Regular Expression

A flaw was found in StackRox/RHACS Central's Auth Machine-to-Machine M2M token exchange. When an administrator configures M2M role mappings, the system uses unanchored regular expressions for matching claim values. This allows an attacker with a valid OpenID Connect OIDC token, whose claim value ...

Diversity Matters: Distributional Feature Coverage Sample Selection for Data-Efficient Backdoor Attacks

Backdoor attacks compromise training data so that a model retains clean accuracy but predicts an attacker-chosen target on triggered inputs. At very low poisoning rates, only a few samples convey the trigger--target association, making poison-sample selection critical. Existing methods typically...

An account holding the nexus:selectors:create permission could construct an expression that read Java object properties not intended to be exposed to the expression engine, disclosing internal JVM class metadata...

kernel: Arm Processors: Privilege escalation or information disclosure via writes to higher exception level resources

A flaw was found in the Linux kernel on ARM processors. A race condition in Translation Lookaside Buffer Invalidation TLBI operations during memory permission changes allows a local attacker to write to memory resources owned by higher privilege levels. This could allow an unprivileged local...

kernel: KVM: x86: Don't (re)check L1 intercepts when completing userspace I/O

A flaw was found in the Kernel-based Virtual Machine KVM for x86. This vulnerability occurs when KVM incorrectly re-checks Level 1 L1 intercepts during the completion of userspace I/O emulation for a Level 2 L2 instruction. If the L1 or host userspace modifies I/O interception settings during thi...
