This vulnerability allows a database user to disclose portions of server memory due to improper validation of the “oidvector” type, which may expose sensitive information under certain conditions. To address this issue, users should upgrade to PostgreSQL versions 18.2, 17.8, 16.12, 15.16, 14.21 or later. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-2003.

In Traefik versions prior to 3.6.8 a high severity vulnerability CVE-2026-25949 was detected. This vulnerability allows an unauthenticated attacker to bypass the entrypoint respondingTimeouts.readTimeout setting by sending the 8-byte Postgres SSLRequest (STARTTLS) prelude and stalling the connection, causing connections to remain open indefinitely and potentially leading to a denial-of-service condition. To address this issue, users should upgrade Traefik to version 3.6.8 or later. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-25949.

In PostgreSQL versions prior to 18.2, 17.8, 16.12, 15.16 and 14.21 a high severity vulnerability CVE-2026-2006 was detected. This vulnerability allows a database user to issue crafted queries that trigger a buffer overrun due to missing validation of multibyte character length in text manipulation functions, potentially leading to arbitrary code execution as the operating system user running the database. To address this issue, users should upgrade PostgreSQL to versions 18.2, 17.8, 16.12, 15.16, 14.21 or later. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-2006.
