Summary
In Percona Monitoring and Management (PMM) server 2.x before 2.37.1, the authenticate function in auth_server.go does not properly formalize and sanitize URL paths, allowing path traversal attacks. This enables an unauthenticated remote user to access protected API routes, leading to privilege escalation and information disclosure.
Risk Assessment
The organization may be exposed to unauthorized access to sensitive data and the potential for privilege escalation by malicious users, which could lead to serious security breaches.
Recommendation
It is recommended to update the PMM server to version 2.37.1 or later to mitigate this vulnerability and implement additional security measures such as monitoring and restricting access to the API.

In Goobi viewer from version 25.08 to before 26.05, the IIIF Auth 2.0 endpoints auth/login and auth/token accept an origin query parameter without validation and embed it into the Content-Security-Policy header and an HTML response body as a postMessage argument. Since the attacker controls both calls, the unescaped value yields reflected XSS.

In conda/conda prior to commit 9c0f238, a GitHub Actions Pwn Request vulnerability remains in .github/workflows/update.yml. It is triggered by comments containing @conda-bot render or @conda-bot recreate, allowing an untrusted PR to reach Jinja2 template rendering in a privileged token context.
- CVE-2026-46652Critical
In Goobi viewer from version 24.03 to before 26.05, ExternalFilesDownloader.getFilename() extracts the filename from a server-supplied Content-Disposition header and passes it directly to Path.resolve() without stripping directory components. A malicious HTTP server can supply an absolute path or ../ sequences, writing attacker-controlled content to an arbitrary path, leading to remote code execution.

In Goobi viewer from version 24.03 to before 26.05, the DownloadTaskEndpoint WebSocket endpoint (/tasks/download/monitor.socket) in goobi-viewer-core accepts download requests from unauthenticated users. This issue has been patched in version 26.05.
- CVE-2026-53921Critical
In odhcpd (the DHCPv6/DHCPv4/RA server used by OpenWrt) prior to version 25.12, the DHCPv6 IA response handler writes past a fixed 512-byte stack buffer (pdbuf) when a single DHCPv6 REQUEST carries enough IA options to nearly exhaust the reply space. Two independent overflow sites exist in the same call chain, both reachable over the network via a single unauthenticated UDP packet. odhcpd runs as root on OpenWrt, and embedded targets often lack stack canaries and ASLR, making code execution realistic.
- CVE-2026-114357Critical
In DJI CrystalSky ZS600C firmware v0.3.9.7 through v0.6.6.9, the Android Debug Bridge daemon (adbd) lacks authentication for a critical function. The device ships with ro.adb.secure=0 and USB ADB enabled by default; once ADB over TCP is enabled, the same unauthenticated shell (uid 2000) is reachable over the network. This provides a foothold for privilege escalation to root.

In PraisonAI from version 4.2.1 to before 4.6.59, the AgentOS FastAPI deployment surface remains unauthenticated despite the earlier fix for CVE-2026-40151. The chat route directly calls agent.chat(request.message), and both no-auth and wrong-bearer requests execute the deployed agent.

Original NVD description (English source)
In Percona Monitoring and Management (PMM) server 2.x before 2.37.1, the authenticate function in auth_server.go does not properly formalize and sanitize URL paths to reject path traversal attempts. This allows an unauthenticated remote user, when a crafted POST request is made against unauthenticated API routes, to access otherwise protected API routes leading to escalation of privileges and information disclosure.
