Critical Gitea Vulnerability CVE-2026-60004 Allows Repository Writers to Execute Commands via Git Hooks

A critical vulnerability catalogued as CVE-2026-60004 in Gitea allows a user with write permissions on a repository to execute arbitrary commands on the server hosting the platform.

The issue arises from the abuse of Git hooks, small scripts that Git can automatically launch at different stages of the development cycle and that can be turned into a vector for injecting system commands.

The key requirement is authenticated access: the attack cannot be launched by an anonymous user and instead needs an account capable of pushing changes, for example a collaborator or any role granted write permissions. This scenario occurs frequently in projects involving multiple teams, repositories shared with third parties, or environments where broad permissions are granted for convenience.

The risk becomes especially severe in organizations that rely on Gitea as part of their internal tooling. The server often maintains visibility into the corporate network, access to shared storage, and proximity to secrets that power daily operations, ranging from access tokens for repositories and container registries to CI/CD credentials and keys used in automated deployments.

The priority response consists of applying the security update; Gitea 1.27.1 is cited as the patched version. Administrators should immediately review the attack surface introduced by Git hooks, disable them if they are not essential, and restrict their use to the minimum required scope. It is also necessary to audit repositories that accept external collaborators, tighten write permissions, and inspect hook-related storage for unauthorized scripts if any anomalous activity is detected.

The existence of a publicly available proof-of-concept raises operational urgency. When a flaw already has reproducible demonstrations, the window for reaction narrows considerably. In suspected compromise scenarios, defenders should rotate credentials and tokens that the Gitea server could access, especially those linked to automation and deployments.

SOC Incident Analysis Exposes Active Exploitation of CVE-2025-53770 SharePoint ToolShell Auth Bypass and RCE

A detailed walkthrough of Letsdefend SOC342 demonstrates how analysts detected and confirmed exploitation of CVE-2025-53770 targeting SharePoint servers. The alert was triggered by a suspicious unauthenticated POST request to ToolPane.aspx carrying an unusually large payload and a spoofed referer. Investigation revealed that the vulnerable server accepted the request, after which PowerShell commands extracted ASP.NET cryptographic keys, enabling ViewState forgery and remote code execution. Attackers then compiled and dropped additional payloads using csc.exe and created a malicious spinstall0.aspx page that leveraged WScript.Shell to download further malware. Network indicators included the malicious IP 107.191.58.76 flagged by CISA and multiple VirusTotal detections. The server was isolated, files removed, and cryptographic keys rotated to contain the breach.
