Kimai: Default APP_SECRET in Docker Image Enables Cookie Forgery and Account Takeover

Summary The official Kimai Docker image ships with APPSECRET=changethistosomethingunique as the default environment variable. The Docker entrypoint does not override or validate this value. Any Kimai instance deployed using the Docker image without explicitly setting APPSECRET runs with a...

kas checks out SHA-like git branches as valid commits

ImpactWhen relying solely on a git commit ID SHA-1 or SHA-256 to qualify if a checkout of a repository is equivalent to the state validated while adding its commit ID to a kas configuration, users may be tricked to check out a branch of the same name from this repository. This implies that the...

SFDS: Selective File Disclosure System

Access control to networked resources has been a longstanding challenge. The conventional solution relies on authentication mechanisms, which introduce additional complexities associated with Identity and Access Management IAM. Such systems require user authentication, identity management, and...

TencentOS Server 4: shim (TSSA-2026:0499)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2026:0499 advisory. Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:...

CVE-2026-56360 n8n - Webhook Forgery via Unsigned POST Requests in ZendeskTrigger

n8n before versions 1.123.18 and 2.6.2 fails to verify HMAC-SHA256 signatures on Zendesk webhooks in the ZendeskTrigger node. Attackers who know the webhook URL can send unsigned POST requests to trigger workflows with arbitrary malicious data...

Git Hash Chain Malleability

This whitepaper demonstrates that signed Git commits are not uniquely bound to their commit hashes, even when they display a valid "Verified" badge on GitHub. The authors show that attackers can transform the signature encoding of an existing signed commit—without possessing the private signing...

Authlib is vulnerable to Denial of Service via Oversized JOSE Segments

SummaryAuthlib’s JOSE implementation accepts unbounded JWS/JWT header and signature segments. A remote attacker can craft a token whose base64url‑encoded header or signature spans hundreds of megabytes. During verification, Authlib decodes and parses the full input before it is rejected, driving...
