An on-path attacker can inject specific patterns to cause catastrophic backtracking, resulting in denihttps://patchthecve.com/cve/CVE-2026-8881.htmlhttps://patchthecve.com/cve/CVE-2026-8881.htmlWed, 22 Jul 2026 20:10:00 +0000HIGH 7.5: Version 3.0.7 of the Securly Chrome Extension uses EVP_BytesToKey key derivation with MD5 and a single iteration for AES encryption. MD5 has been broken since 2004 and a single iteration provides no key stretching.https://patchthecve.com/cve/CVE-2026-8879.htmlhttps://patchthecve.com/cve/CVE-2026-8879.htmlWed, 22 Jul 2026 20:10:00 +0000HIGH 7.5: Version 3.0.7 of the Securly Chrome Extension dynamically registers content13.min.js as a content script via chrome.scripting.registerContentScripts() at runtime. This script is NOT declared in manifest.json and bypasses Chrome Web Store static security review.

The exposed information consists of SHA-1 hashes that are inadequately obfuscated using a simple Caesar cipher, which can be easily reversed to recover thhttps://patchthecve.com/cve/CVE-2026-8876.htmlhttps://patchthecve.com/cve/CVE-2026-8876.htmlWed, 22 Jul 2026 20:10:00 +0000HIGH 7.3: Version 3.0.7 of the Securly Chrome Extension contains hardcoded, plaintext AES passphrases in securly.min.js. These keys decrypt crisis alert keyword data and intervention site data.https://patchthecve.com/cve/CVE-2026-8874.htmlhttps://patchthecve.com/cve/CVE-2026-8874.htmlWed, 22 Jul 2026 20:10:00 +0000HIGH 7.1: Version 3.0.7 of the Securly Chrome Extension downloads JSON files containing crisis alert keywords and filtering rules over unencrypted HTTP via the Fetch API. Other endpoints in the same extension correctly fetch IWF and CIPA data over HTTPS, demonstrating an inconsistent implementation of TLS.
