Vulnerability Title
SSRF bypass via IPv4-mapped IPv6 literals
Vulnerability Description
Mattermost versions 11.3.x <= 11.3.0, 11.2.x <= 11.2.2, 10.11.x <= 10.11.10 fail to canonicalize IPv4-mapped IPv6 addresses before reserved IP validation which allows an attacker to perform SSRF attacks against internal services via IPv4-mapped IPv6 literals (e.g., [::ffff:127.0.0.1]).. Mattermost Advisory ID: MMSA-2026-00585

Mattermost 安全漏洞
Vulnerability Description
Mattermost是美国Mattermost公司的一个开源协作平台。 Mattermost 11.3.0及之前的11.3.x版本、11.2.2及之前的11.2.x版本和10.11.10及之前的10.11.x版本存在安全漏洞，该漏洞源于在保留IP验证前未规范化IPv4映射的IPv6地址，可能导致攻击者通过IPv4映射的IPv6字面量对内部服务执行SSRF攻击。
