Descripción resumida

tj-actions/changed-files GitHub Action contains an embedded malicious code vulnerability that allows a remote attacker to discover secrets by reading Github Actions Workflow Logs. These secrets may include, but are not limited to, valid AWS access keys, GitHub personal access tokens (PATs), npm tokens, and private RSA keys.

Acción requerida

Apply mitigations as set forth in the CISA instructions linked below. Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Notas

This vulnerability affects a common open-source project, third-party library, or a protocol used by different products.

Descripción técnica

tj-actions changed-files before 46 allows remote attackers to discover secrets by reading actions logs. (The tags v1 through v45.0.7 were affected on 2025-03-14 and 2025-03-15 because they were modified by a threat actor to point at commit 0e58ed8, which contained malicious updateFeatures code.)

——4IO::Socket::SSL::SelfCertificate versions 1.00 for Perl contains malware which executes Python code from an obfuscated URL. The generate_certificate runs a Python script saved as a certificate file. The pyhton script attempts to retrieve code from a hardcoded http URL that is obfuscated with base64 encoding and run the response body directly. The impact is that arbitrary code can be invoked as the user, without a dropped script being saved on the affected host. The releases have no test scripts nor build hooks. The intention may have been to trigger the payload after installation. The dropper script is in lib/Crypt/SelfCertificate/sample/cert.pem. This is similar to CVE-2026-95831 for the module Crypt::SelfCertificate. The SHA-256 digests of the files are ba24ee8ec3b7f47f65bed62e16fb413ace50653cf44bd8ea90914390922831e0 IO-Socket-SSL-SelfCertificate-1.00.tar.gz 821d38830e5eb8607738421c25ac25f59fff02a6ab67daa32fbd020429454dac IO-Socket-SSL-SelfCertificate-1.00/lib/IO/Socket/SSL/SelfCertificate/sample/cert.pem d483cb7b23b7271cb11cf242bff4a2e1c02df0b9525eb0429abeea8961c399d5 IO-Socket-SSL-SelfCertificate-1.00-upload.tar.gz20d CVE-2026-958317.8 ALT
