Description
This security bulletin contains information about 2 vulnerabilities.
1) Prototype pollution (CVE-ID: CVE-2025-13465)
CWE-ID: CWE-1321 - Improperly Controlled Modification of Object Prototype Attributes (\'Prototype Pollution\')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to alter application's behavior.
The vulnerability exists due to improper input validation within the in the _.unset and _.omit functions. A remote attacker can pass specially crafted input to the application and delete methods from global prototypes.
2) Prototype pollution (CVE-ID: CVE-2026-2950)
CWE-ID: CWE-1321 - Improperly Controlled Modification of Object Prototype Attributes (\'Prototype Pollution\')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to modify object prototype attributes.
The vulnerability exists due to improper control of object prototype modification in _.unset and _.omit when processing array-wrapped path segments. A remote attacker can pass crafted path segments to modify object prototype attributes.
The bypass affects checks that only guard against string key members. The issue permits deletion of properties from built-in prototypes such as Object.prototype, Number.prototype, and String.prototype, but does not allow overwriting their original behavior.
