HighCVSS 8.6Exploitation Probability (EPSS)
Low risk46th percentile - higher than 46% of all known CVEs
Summary
Config::IniFiles for Perl before 3.001000 uses a two-argument open() for the -file argument, allowing OS command injection or file overwrite if the filename starts or ends with a pipe (|) or redirect (>).
Risk Assessment
An attacker can execute arbitrary system commands or overwrite files on the server, potentially leading to system compromise.
Recommendation
Upgrade Config::IniFiles to version 3.001000 or later.

N-central is vulnerable to pre-auth remote code execution. This issue affects N-central before version 2026.3.1.14.
- CVE-2026-75816Critical
The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to Authentication Bypass to Account Takeover in all versions up to and including 3.29.12. The pre_update_value function lacks capability or ownership checks, and ActionPost::conditions_logic() short-circuits the current_user_can('edit_post') authorization gate when the post ID is non-numeric, allowing unauthenticated form submissions to be routed to arbitrary user records. This enables unauthenticated attackers to overwrite any user's email address, including an administrator's, and then use WordPress's native password-reset flow to take over the account.
- CVE-2026-16310Critical
The MemberDash plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to and including 1.8.5 via the 'id' parameter due to missing validation on a user-controlled key. This allows unauthenticated attackers to change the password of any WordPress user, including administrators, by supplying an arbitrary user ID during registration, and take over their account without any notification to the victim.

Original NVD description (English source)
Config::IniFiles versions before 3.001000 for Perl allow OS command injection and file overwrite via a 2-arg open() of the -file argument in _make_filehandle. Config::IniFiles::_make_filehandle opens a filename argument with Perl's 2-arg open(), so a filename that begins or ends with a pipe ("| cmd", "cmd |") or begins with a redirect ("> path", ">> path") is run as a command or redirect rather than opened as a file. The helper is the open path behind the documented -file argument: new(-file => $thing) reaches it through ReadConfig. An in-memory scalar reference (-file => \$text) does not open a path and is unaffected. Any caller that forwards untrusted input to the -file argument can run an arbitrary command or truncate a file under the process UID.
