Description

This security bulletin contains information about 1 vulnerability.


1) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2026-69192)

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to bypass network trust boundaries and perform server-side request forgery.

The vulnerability exists due to improper input validation in the Address4 parser when processing user-supplied IPv4 addresses with leading-zero octets. A remote attacker can supply a specially crafted address string to bypass network trust boundaries and perform server-side request forgery.

This issue occurs because the library interprets leading-zero octets as decimal while common URL parsers and resolvers interpret them as octal, causing security checks such as private-address and subnet classification to disagree with the destination actually reached by the network stack.
