CVE-2026-33634 NOMISEC HIGH SCANNER
Trivy ecosystem supply chain briefly compromised
Trivy is a security scanner. On March 19, 2026, a threat actor used compromised credentials to publish a malicious Trivy v0.69.4 release, force-push 76 of 77 version tags in `aquasecurity/trivy-action` to credential-stealing malware, and replace all 7 tags in `aquasecurity/setup-trivy` with malicious commits. This incident is a continuation of the supply chain attack that began in late February 2026. Following the initial disclosure on March 1, credential rotation was performed but was not atomic (not all credentials were revoked simultaneously). The attacker could have use a valid token to exfiltrate newly rotated secrets during the rotation window (which lasted a few days). This could have allowed the attacker to retain access and execute the March 19 attack. Affected components include the `aquasecurity/trivy` Go / Container image version 0.69.4, the `aquasecurity/trivy-action` GitHub Action versions 0.0.1 – 0.34.2 (76/77), and the`aquasecurity/setup-trivy` GitHub Action versions 0.2.0 – 0.2.6, prior to the recreation of 0.2.6 with a safe commit. Known safe versions include versions 0.69.2 and 0.69.3 of the Trivy binary, version 0.35.0 of trivy-action, and version 0.2.6 of setup-trivy. Additionally, take other mitigations to ensure the safety of secrets. If there is any possibility that a compromised version ran in one's environment, all secrets accessible to affected pipelines must be treated as exposed and rotated immediately. Check whether one's organization pulled or executed Trivy v0.69.4 from any source. Remove any affected artifacts immediately. Review all workflows using `aquasecurity/trivy-action` or `aquasecurity/setup-trivy`. Those who referenced a version tag rather than a full commit SHA should check workflow run logs from March 19–20, 2026 for signs of compromise. Look for repositories named `tpcp-docs` in one's GitHub organization. The presence of such a repository may indicate that the fallback exfiltration mechanism was triggered and secrets were successfully stolen. Pin GitHub Actions to full, immutable commit SHA hashes, don't use mutable version tags.

CVE-2026-3888 NOMISEC HIGH WORKING POC
Local Privilege Escalation in snapd
Local privilege escalation in snapd on Linux allows local attackers to get root privilege by re-creating snap's private /tmp directory when systemd-tmpfiles is configured to automatically clean up this directory. This issue affects Ubuntu 16.04 LTS, 18.04 LTS, 20.04 LTS, 22.04 LTS, and 24.04 LTS.

CVE-2026-0628 NOMISEC HIGH WORKING POC
Google Chrome < 143.0.7499.192 - Insufficient Policy Enforcement in WebView Tag
Insufficient policy enforcement in WebView tag in Google Chrome prior to 143.0.7499.192 allowed an attacker who convinced a user to install a malicious extension to inject scripts or HTML into a privileged page via a crafted Chrome Extension. (Chromium security severity: High)

CVE-2025-4679 NOMISEC MEDIUM WORKING POC
Synology Active Backup for Microsoft 365 - Info Disclosure
A vulnerability in Synology Active Backup for Microsoft 365 allows remote authenticated attackers to obtain sensitive information via unspecified vectors.

CVE-2025-20343 NOMISEC HIGH WRITEUP
Cisco Identity Services Engine - Denial of Service via RADIUS Request Processing
A vulnerability in the RADIUS setting Reject RADIUS requests from clients with repeated failures on Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to cause Cisco ISE to restart unexpectedly. This vulnerability is due to a logic error when processing a RADIUS access request for a MAC address that is already a rejected endpoint. An attacker could exploit this vulnerability by sending a specific sequence of multiple crafted RADIUS access request messages to Cisco ISE. A successful exploit could allow the attacker to cause a denial of service (DoS) condition when Cisco ISE restarts.

CVE-2025-29943 NOMISEC MEDIUM WORKING POC
AMD EPYC 9004/9005/8004, Embedded 7003/9005 - Write-What-Where via CPU Pipeline Config
Write what were condition within AMD CPUs may allow an admin-privileged attacker to modify the configuration of the CPU pipeline potentially resulting in the corruption of the stack pointer inside an SEV-SNP guest.
CVE-2024-42461 NOMISEC CRITICAL WRITEUP
elliptic 6.5.6 - Improper Verification of Cryptographic Signature via BER-Encoded ECDSA Signatures
In the Elliptic package 6.5.6 for Node.js, ECDSA signature malleability occurs because BER-encoded signatures are allowed.

CVE-2024-3094 NOMISEC CRITICAL SCANNER
xz <5.6.0 - Code Injection
Malicious code was discovered in the upstream tarballs of xz, starting with version 5.6.0. Through a series of complex obfuscations, the liblzma build process extracts a prebuilt object file from a disguised test file existing in the source code, which is then used to modify specific functions in the liblzma code. This results in a modified liblzma library that can be used by any software linked against this library, intercepting and modifying the data interaction with this library.

CVE-2026-21858 VULNCHECK_XDB CRITICAL WRITEUP
n8n 1.65.0-1.120.9 - Unauthenticated Arbitrary File Read via Form-Based Workflow Execution
n8n is an open source workflow automation platform. Versions starting with 1.65.0 and below 1.121.0 enable an attacker to access files on the underlying server through execution of certain form-based workflows. A vulnerable workflow could grant access to an unauthenticated remote attacker, resulting in exposure of sensitive information stored on the system and may enable further compromise depending on deployment configuration and workflow usage. This issue is fixed in version 1.121.0.
