PHP zero-day RCE pair triggers global patching scramble as FBI and NSA urge offline mitigation
PHP 内核爆出两个严重未认证远程代码执行漏洞 CVE-2026-109618 与 CVE-2026-109619(CVSS 9.2,被称作 PHP2Shell),官方于 10 月 22 日紧急发布 8.5.12/8.4.27/8.3.36/8.2.35 修复版本。由于漏洞信息提前泄露、协调披露流程被破坏,补丁公开即意味着攻击者可逆向定位漏洞,各方以「分钟级」节奏应急,FBI 与 NSA 罕见发出近乎强制性的全球警报。
已确认
- PHP 发布四个紧急版本修复两个关联 RCE 漏洞,条件满足时未认证攻击者可在服务器上执行代码,官方呼吁立即升级(m5)。
- CVE-2026-109618 指请求恰好落在特定条件下即可触发;漏洞位于 PHP 解释器内核而非应用层(m5、m11)。
- 原本应非公开准备的修复因信息提前泄露被迫提前发布,安全企业预警修复版公开约 15 分钟内预计出现大规模攻击(m2)。
- FBI 网络部门发布全球警报,NSA 发出罕见强制性通告:无法立即更新的组织应将系统离线直至缓解(m3、m4、m10)。
- 漏洞公开后,欧洲多国政府网站与日本 pixiv、Niconico 等平台紧急下线维护(m11)。
- 据转发帖流传的数字,PHP 驱动全球约 43%–80% 的网页(不同帖子口径不一:43%、约七成、80%)。
- PHP 基金会披露,今年早些时候 Anthropic 的 Claude 曾扫描 PHP 代码库,且可用 OpenAI 的 Daybreak Red 验证漏洞利用(m8)。
尚未确认
- 「约七成/80% 网站」等受影响面数字来自转发科普帖,口径不一,官方通告中的精确比例未在材料中直接给出。
- 是否已出现在野利用:m10 推测「可能已有在野利用」,但材料中无确证。
为什么重要
- 这是罕见的「补丁未出、漏洞先泄」情形:修复代码本身即暴露漏洞位置,把通常以天计的加固窗口压缩到分钟级,被视为安全应急范式的一次压力测试。
- AI 角色引人注目:APPSO 指出 AI 一周完成过去需数月的漏洞验证;Ethan Mollick(经 m6 转述)称这是攻防以非人速度加速的可见信号。同时 teortaxesTex 调侃,若自主 agent 没趁此零门槛窗口攻陷三分之一的互联网,大家就该下调自己的 p(doom)——既是玩笑也是对 AI 风险叙事的一次现实校验。
