Security readout for executives and security teams
Plain-English summary
The Joomla IP Login extension used persistent URL login keys generated with weak, insufficiently random values. An unauthenticated network attacker may be able to guess valid keys and access protected accounts, exposing or altering sensitive information. The listed affected range is versions 1.0.0 through 6.2.5.
Executive priority
Treat this as an urgent identity and access risk. Prioritize externally reachable Joomla systems and installations protecting sensitive or administrative access. Establish exposure immediately, follow confirmed vendor guidance, and investigate suspicious authentication activity; the sources do not name a fixed version.
Technical view
CVE-2026-64798 is a CWE-338 weakness in Regular Labs IP Login for Joomla. Persistent URL login keys use a non-cryptographic random generator with insufficient entropy. CVSS 3.1 rates exploitation as network-accessible, low complexity, requiring neither privileges nor user interaction, with high confidentiality and integrity impact but no stated availability impact.
Likely exposure
Exposure is most likely where Joomla runs IP Login versions 1.0.0 through 6.2.5 and URL-key authentication is enabled or network-reachable. The bundle does not quantify installations, identify default configuration, or confirm whether every installation generates persistent keys.
Exploitation context
The supplied record does not report active exploitation, KEV listing, or a public exploit. Nevertheless, the 9.1 vector indicates potentially remote, unauthenticated, low-complexity abuse. No exploit method, observed campaign, or reliable attack prevalence is established by the available sources.
Researcher notes
The record identifies insufficient entropy and non-cryptographic key generation but provides no algorithm, entropy measurement, key length, endpoint detail, fixed version, or reproduction evidence. The affected range is listed as 1.0.0–6.2.5, with versions outside that range defaulting to unaffected. Avoid assuming exploitability details beyond the CVSS vector.
Mitigation direction
- Inventory Joomla deployments for Regular Labs IP Login versions 1.0.0 through 6.2.5.
- Check the CVE record and Regular Labs guidance for a confirmed fixed release or supported mitigation.
- Consider disabling the affected extension under change control until authoritative remediation guidance is applied.
- After remediation, invalidate existing persistent URL login keys if product controls permit.
Validation and detection
- Confirm the installed extension version and whether URL-key authentication is enabled and network-reachable.
- Verify vendor-recommended remediation is applied consistently across every affected Joomla deployment.
- Test that previous persistent keys no longer authenticate after remediation, if safe invalidation testing is supported.
- Review authentication logs for unusual IP Login activity and unexpected account access.

Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)
Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
