CVE-2026-81525 is an improper neutralization vulnerability in the MongoDB PHP library's handling of application-supplied database and collection namespace identifiers. Period and NUL-byte characters are not sufficiently sanitized before identifiers are used to construct MongoDB operation targets. Where an application incorporates untrusted text into these identifiers, an attacker can cause reads, writes, or other database operations to resolve to a namespace different from the one intended by the application.
