In OpenLDAP 2.x before 2.5.12 and 2.6.x before 2.6.2 a SQL injection vulnerability exists in the experimental back-sql backend to slapd via a SQL statement within an LDAP query. This can occur during an LDAP search operation when the search filter is processed due to a lack of proper escaping.

Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability? One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
