CVE-2026-111262 · Severity: info · Published 2026-11-10

Jakarta Security provides authentication mechanisms for Java applications, including an LDAP identity store that connects to directory services. An attacker can inject special characters into login queries to enumerate user accounts, extract directory information, or bypass authentication controls without needing to authenticate first.

Technologies: [Apache Jakarta Security](https://junglewise.ai/threats/technologies/jakarta-security). Vendors: [Apache](https://junglewise.ai/threats/vendors/apache).

## How to fix

- Fixed in 10.3.0, 11.0.0-M2

## Technical details

The LDAP identity store fails to sanitize special characters in the caller name before constructing directory queries, enabling LDAP injection attacks. An unauthenticated remote attacker can manipulate queries via the login parameter to enumerate accounts, infer attribute values, or alter which directory entry validates the login. The vulnerability is present in versions prior to 10.3.0 and 11.0.0-M2.

## Affected products

- Apache Jakarta Security before 10.3.0 and 11.0.0-M2
