Summary
The GD library for Perl before version 2.86 has an OS command injection and file overwrite vulnerability in the _make_filehandle function. It opens a filename argument with Perl's 2-arg open(), which interprets prefixes like '| cmd' as a pipe, allowing arbitrary command execution or file overwrite.
Risk Assessment
An attacker can pass untrusted filenames to GD::Image constructors, leading to arbitrary command execution or file destruction with process privileges.
Recommendation
Upgrade the GD library to version 2.86 or later, and avoid passing untrusted data as filenames to GD::Image functions.

A weakness has been identified in Totolink A3002MU version 1.0.0-B20230403.1455. It affects the function sub_40FCFC in the file /bin/boa of the Authentication Check component. Executing a manipulation can lead to improper authorization. The attack can be launched remotely, and the exploit has been made publicly available.
- CVE-2026-103510Critical
P4 Search prior to 2026.4.2 does not fail securely when its service authentication token is blank. In affected configurations, an unauthenticated attacker with network access can obtain the highest application privilege, potentially leading to compromise of P4 Search and the connected P4 Server.
- CVE-2026-100103Critical
Perforce P4 Search container images prior to 2026.4.2 reset the service authentication token to a publicly documented default value. An unauthenticated attacker with network access can obtain the highest application privilege, potentially leading to arbitrary code execution and compromise of the connected P4 Server.
- CVE-2026-100102Critical
Perforce P4 Search container images prior to 2026.4.2 enable an unauthenticated Java debug interface. An attacker with network access to this interface can execute arbitrary code as the P4 Search service account, potentially leading to compromise of the connected P4 Server.

ZITADEL before 3.4.14 and 4.x before 4.16.2 contains an authentication bypass in the hosted Login V1 UI because the 'external account not found' registration endpoint trusts client-supplied external identity fields without a completed IdP callback. Unauthenticated attackers can submit forged IDPConfigID and ExternalUserID values to pre-create an account bound to a victim's external IdP identity, which the victim's later genuine external login then signs into.
- CVE-2026-105209Critical
ZITADEL 3.x before 3.4.15 and 4.x before 4.17.1 contains an improper authorization vulnerability: when issuing passkey or passwordless enrollment codes, it checks only the organization in the x-zitadel-orgid header, not the target user's organization. Attackers with user-write permission in one organization can obtain an enrollment code for a user in another organization on the same instance and register their own authenticator to take over that account.
- CVE-2026-105207Critical
ZITADEL 3.0.0 through 3.4.15 and 4.0.0 before 4.17.3 creates links between user accounts and external identity providers without verifying a primary factor or the caller's permission, including on identify-only Login V2 sessions and via the User Service V2 AddIDPLink endpoint. An unauthenticated attacker knowing a victim's login name can bind their own external IdP identity to the victim's account and then sign in as the victim.

Original NVD description (English source)
GD versions before 2.86 for Perl allow OS command injection and file overwrite via a 2-arg open() of filename arguments in _make_filehandle. GD::Image::_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. _make_filehandle is the single open path behind every filename-accepting constructor (new, newFromPng, newFromJpeg, and the rest); the in-memory *Data variants do not open a path and are unaffected. Any caller that forwards untrusted input to one of these constructors as a pathname can run an arbitrary command or truncate a file under the process UID.
