Temporal Server: attacker-controlled namespace could signal, delete, and reset workflows or activities in a victim namespace on the same cluster

A writer role user in an attacker-controlled namespace could signal, delete, and reset workflows or activities in a victim namespace on the same cluster. Exploitation requires the attacker to know or guess specific victim workflow IDs and, for signal operations, signal names. This was due to a bu...

CVE-2026-5199

The CVE-2026-5199 issue arises from a bug in Temporal Server v1.29.0 where a writer in an attacker-controlled namespace could signal, delete, or reset workflows/activities in a victim namespace on the same cluster. The root cause is that the batch activity validated the victim namespace ID but di...

CSTS: A Canonical Security Telemetry Substrate for AI-Native Cyber Detection

AI-driven cybersecurity systems often fail under cross-environment deployment due to fragmented, event-centric telemetry representations. We introduce the Canonical Security Telemetry Substrate CSTS, an entity-relational abstraction that enforces identity persistence, typed relationships, and...

The vulnerability of the Django web application platform, related to the disclosure of information based on temporal discrepancies, allows attackers to gain unauthorized access to protected information.

The vulnerability of the Django web application framework is related to the disclosure of information based on temporal discrepancies. Exploiting this vulnerability can allow an attacker operating remotely to gain unauthorized access to protected information...

Two Frames Matter: A Temporal Attack for Text-To-Video Model Jailbreaking

Recent text-to-video T2V models can synthesize complex videos from lightweight natural language prompts, raising urgent concerns about safety alignment in the event of misuse in the real world. Prior jailbreak attacks typically rewrite unsafe prompts into paraphrases that evade content filters...

CVE-2026-23808

A vulnerability has been identified in a standardized wireless roaming protocol that could enable a malicious actor to install an attacker-controlled Group Temporal Key GTK on a client device. Successful exploitation of this vulnerability could allow a remote malicious actor to perform unauthoriz...
