PYSEC-2026-1526 Langflow Vulnerable to Privilege Escalation via CLI Superuser Creation (Post-RCE)

This vulnerability was discovered by researchers at Check Point. We are sharing this report as part of a responsible disclosure process and are happy to assist in validation and remediation if needed. Summary A privilege escalation vulnerability exists in Langflow containers where an authenticate...

PYSEC-2026-1911 Sentry vulnerable to leaking superuser cleartext password in logs

Impact When authenticating as a superuser to a self-hosted Sentry instance with a username and password, the password is leaked as cleartext in logs under the event: auth-index.validatesuperuser. An attacker with access to the log data could use these leaked credentials to login to the Sentry...

GHSA-R35R-FPX2-JGR4 Linuxfabrik Monitoring Plugins allow insecure creation of SQLite databases

Summary The SQLite databases are created at predictable static paths in /tmp. Any user can therefore create a symlink at these paths in /tmp pointing to arbitrary files. The monitoring scripts then follows these symlinks and then creates their database at the symlink target. This becomes really...

postgresql: PostgreSQL: Operating system account hijack via symlink following in pg_basebackup and pg_rewind

A flaw was found in PostgreSQL. This vulnerability, related to symlink following in pgbasebackup plain format and pgrewind, allows an origin superuser to overwrite local files. By exploiting this, an attacker could potentially hijack the operating system account. This attack has practical...

Security Bulletin: Unauthenticated Superuser Token Issuance via Auto-Login Endpoint

Summary An unauthenticated endpoint in the login API allowed any network-reachable attacker to obtain a 365-day superuser bearer token without requiring any credentials. The /api/v1/login/autologin endpoint issued tokens when the AUTOLOGIN configuration defaulted to True, enabling complete...

PT-2026-60833

Name of the Vulnerable Software and Affected Versions IBM Langflow OSS versions 1.0.0 through 1.10.0 Description Unauthenticated attackers can achieve remote code execution RCE on default deployments by chaining two endpoints. First, the '/api/v1/auto login' endpoint allows the minting of SUPERUS...

postgresql: PostgreSQL libpq: Buffer overflow allows server superuser to overwrite client stack memory

A flaw was found in PostgreSQL libpq. A server superuser can exploit a buffer overflow vulnerability in the PQfn function, which is used by client functions such as loexport, loread, lolseek64, and lotell64. This allows the superuser to send an arbitrarily large response, overwriting the client's...
