Vvveb: Generation of Error Message Containing Sensitive Information
CVE-2026-41935 is a high-severity generation of error message containing sensitive information vulnerability in Vvveb from Givanz, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 1.0.8.3 as the first without the flaw, so updating Vvveb to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.27% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Vvveb to 1.0.8.3 or a later version.

Official description
Vvveb before 1.0.8.3 contains an uncontrolled recursion vulnerability in the admin controller dispatch cycle where Base::init() repeatedly invokes permission() on error handlers, causing infinite recursion until PHP memory limits are exhausted. Attackers can send sustained requests to forbidden admin URLs from a low-privilege account to exhaust PHP memory on all workers and cause denial of service to legitimate traffic.

The underlying weakness: Generation of Error Message Containing Sensitive Information
The product generates an error message that includes sensitive information about its environment, users, or associated data.
How developers prevent this class of flaw
- Handle exceptions internally and do not display errors containing potentially sensitive information to a user.
- Use naming conventions and strong types to make it easier to spot when sensitive data is being used. When creating structures, objects, or other complex entities, separate the sensitive and non-sensitive data as much as possible.
- Debugging information should not make its way into a production release.
