CVE-2026-42568 Maven MEDIUM PATCH GHSA This Month

LDAP injection in Yamcs LdapAuthModule (yamcs-core < 5.12.7) enables horizontal privilege escalation for authenticated low-privilege users. By submitting a wildcard character as the username alongside a single known valid LDAP password, an attacker causes the unescaped LDAP search filter to match the first user returned by the directory query, effectively authenticating as that account. A proof-of-concept exploit is publicly available in the GitHub advisory; no CISA KEV listing exists, but the low attack complexity and published PoC make this a credible threat for any Yamcs deployment using LDAP authentication.

CVE-2026-44063 MEDIUM PATCH This Month

LDAP filter injection in Netatalk 2.1.0 through 4.4.2 enables an authenticated remote attacker to manipulate LDAP query logic, potentially reading or modifying directory entries beyond their authorization scope. The CVSS score of 4.2 (Medium) reflects real but bounded impact - high attack complexity and a requirement for low-privilege authentication constrain opportunistic exploitation. No public exploit code has been identified at time of analysis, and this CVE is not listed in the CISA KEV catalog.

CVE-2026-44671 Go HIGH PATCH GHSA This Week

LDAP Filter Injection in Zitadel's identity provider implementation allows unauthenticated remote attackers to enumerate valid usernames and extract sensitive LDAP directory attributes through blind injection techniques. The vulnerability exists in Zitadel versions 2.71.11-2.71.19, 3.1.0-3.4.9, and 4.0.0-4.14.0 when LDAP is configured as an identity provider. Exploitation requires no authentication (CVSS PR:N) and has network attack vector (AV:N) with low complexity (AC:L), resulting in high confidentiality impact (C:H) but no authentication bypass capability. Vendor-released patches are available for 3.x (3.4.10) and 4.x (4.15.0) branches. No public exploit identified at time of analysis, though the attack technique is well-documented in security research.

CVE-2026-44304 PyPI HIGH PATCH GHSA This Week

LDAP filter injection in Netflix Lemur certificate management platform allows authenticated users with valid LDAP credentials to escalate privileges to administrator by injecting metacharacters into the username field during login. Attackers manipulate group membership queries to gain unauthorized admin roles, enabling access to all certificates, private keys via /certificates/<id>/key endpoint, and CA configurations. Vendor-released patch confirmed in version 1.9.0 (GitHub advisory GHSA-3r34-vq8m-39gh). CVSS 8.1 indicates high confidentiality and integrity impact with low attack complexity from network-authenticated attackers. No public exploit code identified at time of analysis, though detailed reproduction steps exist in the advisory.

Incomplete LDAP query escaping in PowerDNS Authoritative with 8bit-dns enabled allows authenticated users to enumerate internal domain subtrees through LDAP injection, leading to information disclosure of sensitive DNS zone data. The vulnerability requires valid authentication, high attack complexity due to LDAP protocol constraints, and has been reported by the vendor security team. No active exploitation data is currently available.

Authentication bypass in mitmproxy 12.2.1 and below allows remote attackers to bypass LDAP-based proxy authentication through unsanitized username injection. The vulnerability affects only instances explicitly configured with the proxyauth option using LDAP authentication, which is disabled by default. Attackers can exploit this over the network without authentication or user interaction to gain unauthorized access to proxied connections.
