MISP Installer Log and FIFO Created World-Readable, Exposing Sensitive Credentials
cve-program · CVE-2026-95667
PublishedThe MISP installer scripts (for Debian 12, Debian 13, Ubuntu 24.04, and RHEL 9.4) create a log file at /var/log/misp_install.log and a named pipe (FIFO) at /var/log/misp_install.log.pipe to capture all installer output. The log captures highly sensitive data including the generated admin password, database passwords, GPG passphrase, and supervisor password. However, the log file was created by the tee command under the system default umask, resulting in world-readable permissions (typically 0644). Similarly, the FIFO was created with mkfifo without an explicit mode, also inheriting the default umask and remaining world-readable during the window before it was unlinked. Any local unprivileged user on the system could read the log file or the FIFO to obtain these credentials. Additionally, the log file was not removed before creation, meaning a pre-existing symlink in /var/log could have been used to redirect the write to an arbitrary location. Version affected: <2.5.47

Exploitation and risk
Source statusCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
Which CVEs have scores here?
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.
