GHSA-6RH5-QQ4Q-97XH vm2: NodeVM builtin denylist bypass via fs/promises despite -fs, allowing host filesystem writes

Summary NodeVM's builtin wildcard policy can allow sandboxed code to access fs/promises even when the embedder denies fs. With the following configuration: js require: builtin: '', '-fs', '-childprocess' require'fs' and require'childprocess' are blocked, but require'fs/promises' and...

CVE-2026-101087 Nezha 2.0.10 through 2.3.2 SSRF Denylist Bypass IPv6

Nezha versions 2.0.10 through 2.3.2 use a restricted HTTP client to validate user-configurable notification and DDNS webhook URLs, but the denylist did not cover IPv6 transition ranges — specifically the 6to4 prefix 2002::/16 and the local-use IPv4/IPv6 translation prefix 64:ff9b:1::/48. Because...

CVE-2026-101087

Nezha versions 2.0.10 through 2.3.2 are vulnerable to a server-side request forgery (SSRF) denylist bypass. The software uses a restricted HTTP client to validate user-configurable notification and DDNS webhook URLs, but the denylist fails to include specific IPv6 transition ranges, namely the 6t...
