🔒 An unauthenticated attacker could read any file the Gitea service account can access in versions 1.22.1–1.27.0 by posting crafted Org-mode markup to the markup endpoint. The issue, tracked as CVE-2026-59774 and rated Critical (CVSS 9.8), was fixed in Gitea 1.27.1. Self-hosted admins should upgrade immediately and rotate exposed credentials if the endpoint was reached.

🛡️ The Rails project patched a critical Active Storage vulnerability (CVE-2026-66066) that can let unauthenticated attackers read arbitrary files and potentially achieve remote code execution when libvips is used. The flaw affects multiple Rails branches before specified patch releases and requires accepting uploads from untrusted users. Administrators should upgrade libvips to 8.13+, apply Rails updates, and rotate exposed secrets. ImageMagick users are not affected by this vector.

🛡️ Open a repository in Cursor on Windows and, if a file named git.exe is in the project root, Cursor runs it automatically without prompt. Whatever that binary does executes as the logged-in user and Cursor repeatedly spawns it while the project remains open. Mindgard reported the issue in December 2025, published full details seven months later, and no patch or Cursor advisory had been issued as of July 15, 2026.

🔒 The Avada Builder WordPress plugin contained two serious vulnerabilities impacting an estimated one million active installations.

Researchers urge immediate updates, disabling unused extensions, and avoiding untrusted sites while localhost servers run.

⚠️ Siemens NX contains multiple file-parsing vulnerabilities in its handling of CGM files that can cause application crashes or enable arbitrary code execution when a malicious file is opened. Siemens has released fixes and advises updating to V2512 or later. Do not open untrusted CGM files and apply vendor updates promptly. Follow CISA guidance on network isolation and secure remote access.

🔒 Chainlit, a widely used open-source framework for building conversational AI, contained two high-severity flaws that enable arbitrary file reads and server-side request forgery without user interaction. Zafran Labs labeled the issues CVE-2026-22218 and CVE-2026-22219, which together can expose API keys, cloud credentials, source code, and internal services. The defects were fixed in v2.9.4; organizations should upgrade to 2.9.4 or later immediately and inspect for potential data exfiltration.

⚠️ Security researchers disclosed two critical vulnerabilities in the Python-based AI app framework Chainlit that allow unauthenticated attackers to read arbitrary server files and trigger SSRF requests. The flaws (CVE-2026-22218 and CVE-2026-22219), fixed in Chainlit 2.9.4, stem from an unvalidated custom Element type exposing path and URL properties. Exploits can leak environment variables, API keys, LLM prompts, and cloud credentials, enabling lateral movement and broader compromise.

🔒 Chainlit, a widely used framework for building conversational AI applications, contained two server-side vulnerabilities (CVE-2026-22218 and CVE-2026-22219) that allow authenticated users to read arbitrary files and trigger SSRF in affected deployments. The flaws stem from insufficient validation of user-controlled properties in custom elements and SQLAlchemy-backed storage. Combined, they can expose environment variables, cached prompts, API keys and cloud metadata, enabling lateral movement beyond the app layer. Chainlit released 2.9.4 on 24 December 2025 and users are advised to apply the patch immediately; temporary WAF signatures were published as mitigation.

⚠️ A trio of vulnerabilities in mcp-server-git, the official MCP Git server maintained by Anthropic, can be chained to read or delete arbitrary files and, in certain scenarios, achieve remote code execution. Cyata researcher Yarden Porat showed these issues are exploitable via prompt injection when an AI assistant ingests attacker-controlled content such as a malicious README or poisoned issue text. Fixes were released in 2025.9.25 and 2025.12.18; users should update the Python package promptly to mitigate risk.

🔒 Siemens has released a security update for SINEC Security Monitor addressing two vulnerabilities (CVE-2025-40830, CVE-2025-40831) in versions before V4.10.0.
