CVE-2026-33661

CVE-2026-33661 affects the yansongda/pay library prior to 3.7.20. The verify_wechat_sign() function incorrectly bypasses RSA signature verification when the PSR-7 request Host header is localhost, allowing an attacker to POST to the WeChat Pay callback with Host: localhost and forge payment succe...

CVE-2026-33661 WeChat Pay callback signature verification bypassed when Host header is localhost

Pay is an open-source payment SDK extension package for various Chinese payment services. Prior to version 3.7.20, the verifywechatsign function in src/Functions.php unconditionally skips all signature verification when the PSR-7 request reports localhost as the host. An attacker can exploit this...

A vulnerability was identified in Yi Technology YI Home Camera 2 2.1.120171024151200. This impacts an unknown function of the file home/web/ipc of the component HTTP Firmware Update Handler. The manipulation leads to improper verification of cryptographic signature. The attack is possible to be...

FreeBSD Security Advisory - FreeBSD-SA-26:08.rpcsec_gss

FreeBSD Security Advisory - Each RPCSECGSS data packet is validated by a routine which checks a signature in the packet. This routine copies a portion of the packet into a stack buffer, but fails to ensure that the buffer is sufficiently large, and a malicious client can trigger a stack overflow...

PT-2026-28169

Name of the Vulnerable Software and Affected Versions Pay versions prior to 3.7.20 Description The verify wechat sign function in src/Functions.php does not properly validate signatures when the Host header in a PSR-7 request is set to localhost. This allows an attacker to bypass the RSA signatur...
