Descrição resumida

TanStack contains an unspecified vulnerability that allowed malicious versions of the product to be published to the npm registry to publish credential-stealing malware under a trusted identity.

Ação necessária

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 could affect an open-source component, third-party library, protocol, or proprietary implementation that could be used by different products. For more information, please see: https://github.com/TanStack/router/security/advisories/GHSA-g7cv-rxg3-hmpx ; https://nvd.nist.gov/vuln/detail/CVE-2026-45321

Descrição técnica

On 2026-05-11, between approximately 19:20 and 19:26 UTC, 84 malicious versions across 42 @tanstack/* packages were published to the npm registry. The publishes were authenticated via the legitimate GitHub Actions OIDC trusted-publisher binding for TanStack/router, but the publish workflow itself was not modified. The attacker chained three known vulnerability classes — a pull_request_target "Pwn Request" misconfiguration, GitHub Actions cache poisoning across the fork↔base trust boundary, and runtime memory extraction of the OIDC token from the Actions runner process — to publish credential-stealing malware under a trusted identity. Each affected package received exactly two malicious versions, published a few minutes apart.

——16Rank Math SEO PRO for WordPress is affected by a supply-chain compromise in a subset of version 3.0.123 packages downloaded or updated between October 15, 2026 at 20:02 UTC and October 16, 2026 at 07:12 UTC. Rank Math states that the affected plugin files contained malware that could compromise a website if the plugin was activated and directs sites that activated an affected package to treat the website as compromised. The malware may establish persistent access, communicate with rank1cdn[.]com, recreate hidden backdoors on page visits, and expose WordPress credentials, database credentials, API keys, and other secrets accessible to the web server. Rank Math identifies three malicious wp_options keys, hidden PHP backdoors, unauthorized administrator accounts, a fake WordPress core file, PHP-executable .cache files, and a system cron marker as incident indicators. Only packages obtained during the vendor-confirmed window are claimed as affected; version 3.0.123 alone is not sufficient to establish compromise. Rank Math removed the affected files and released version 3.0.124 as the clean replacement.16d CVE-2026-972309.8 CRÍ

——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.gz41d CVE-2026-958317.8 ALT
