espocrm: Insufficiently Protected Credentials
CVE-2026-105833 is a high-severity insufficiently protected credentials vulnerability in espocrm, with a CVSS 3.1 base score of 7.7 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 10.0.5 as the first without the flaw, so updating espocrm to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.22% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

Official description
EspoCRM before 10.0.5 contains an insecure direct object reference vulnerability in PersonalAccount\Service that allows users with Email Account scope access to retrieve other users' IMAP passwords. Attackers who know a victim's Email Account record ID can request that record to steal stored IMAP credentials and access the victim's mailbox.

The underlying weakness: Insufficiently Protected Credentials
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
How developers prevent this class of flaw
- Use an appropriate security mechanism to protect the credentials.
- Make appropriate use of cryptography to protect the credentials.
- Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
