Summary
In Datavane Datavines up to commit 13607645e14a4982468cfdbcf75c85cde63bae71, in TokenManager.java (JWT Token Handler component), manipulation of the tokenSecret argument can lead to use of a hard-coded cryptographic key. The attack is remote, highly complex, and difficult to exploit, and the exploit has been publicly disclosed.
Risk Assessment
Use of a hard-coded cryptographic key may allow forging JWT tokens and bypassing authentication. Although exploitation is difficult, public disclosure of the exploit increases the risk.
Recommendation
Apply patch e540d6dc04e2e6ad11907fb655f3728a13e7b939 or a later release containing it. Configure a unique, random JWT secret instead of a value embedded in code.

imgproxy from 4.0.0 before 4.0.16 contains an integer overflow in the ICO loader that allows remote attackers to trigger a heap buffer overflow via a crafted data_size value. Attackers can submit a crafted ICO image whose data_size wraps the allocation in vips/icoload.c, corrupting heap memory to crash the process or achieve code execution.
- CVE-2026-123551Critical
OpenAM from 14.0.0 before 16.1.4 contains an information disclosure vulnerability that allows unauthenticated attackers to read live session tokens from the notification WebSocket. Attackers can bypass the agent-only check through an unvalidated internal forward on legacy Liberty ID-FF endpoints, collecting iPlanetDirectoryPro tokens to hijack user and administrator sessions.
- CVE-2026-123550Critical
OpenAM before 16.1.4 contains an authentication bypass vulnerability in its SAML v2.0 service provider that accepts unsigned assertions on the ECP (PAOS) and HTTP-Artifact bindings when WantAssertionsSigned is false. Unauthenticated remote attackers can submit forged assertions to obtain sessions as any mapped user, including administrators, and hijack single sign-on to dependent applications.
- CVE-2026-123549Critical
OpenAM before 16.1.4 fails to enforce the Valid Creation Attributes list during self-registration, allowing anonymous attackers to set restricted attributes including group membership. Attackers can register through the legacy self-service REST endpoint or User Self-Service flow to join administrative groups and gain full administrative control of OpenAM.
