Detailsinfo

A vulnerability was found in QloApps up to 1.7.0. It has been rated as problematic. This issue affects the function Tools::encrypt of the file classes/Tools.php. The manipulation with an unknown input leads to a weak password hash vulnerability. Using CWE to declare the problem leads to CWE-916. The product generates a hash for a password, but it uses a scheme that does not provide a sufficient level of computational effort that would make password cracking attacks infeasible or expensive. Impacted is confidentiality. The summary by CVE is:

QloApps through 1.7.0, fixed in commit 64e9722, contains a weak cryptographic algorithm vulnerability that allows attackers to compromise user credentials by exploiting the use of MD5 for password hashing in the Tools::encrypt() function within classes/Tools.php, which concatenates a static cookie key with the supplied password. Attackers can perform offline brute-force attacks against the MD5 hashes, with the risk compounded by auto-generated 8-character passwords assigned during guest-to-customer account conversion in classes/Customer.php, making credential recovery trivial.

The weakness was disclosed by Chia Min Jun Lennon. It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2026-25861 since 02/06/2026.
