CVE-2026-114437
MediumSummary
In the Golang Chi web framework, the ClientIPFromXFF middleware skips any X-Forwarded-For entry in a configured trusted CIDR but never verifies that the direct TCP peer in http.Request.RemoteAddr belongs to that CIDR. A client that can reach the Go server directly can therefore append a trusted-looking entry.
Risk Assessment
An attacker can spoof a trusted IP address, potentially bypassing IP-based access controls or poisoning logs and analytics systems.
Recommendation
Update the Chi framework to a patched version or implement custom verification that http.Request.RemoteAddr belongs to the trusted CIDR before trusting the X-Forwarded-For header.

- CVE-2026-114820Critical
Vulnerability in the JSSE component of Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition. It is easily exploitable by an unauthenticated attacker with network access, leading to unauthorized creation, deletion, or modification of critical data as well as unauthorized access to critical data. The vulnerability also applies to Java deployments that load and run untrusted code in a sandbox (e.g., Java Web Start applications or applets).

Postiz signs its session, invitation and password reset tokens with one shared secret and without any marker of what a token is for. A route that refreshes the credentials of a browser-extension channel signed data taken from the request itself and stored the result where the requesting user can read it back, allowing a user to obtain a validly signed token containing any claims they choose, accepted as a session, an organization invitation with a chosen role, a password reset or an enterprise provisioning token.

Python has added a denylist for known compromised certificates to the "ssl" module to ensure user safety even without certificate revocation configured. Known compromised certificates will automatically be rejected regardless of the SSLContext policy configuration.
- CVE-2026-115932Critical
In Postiz, a media path that is not a web address is treated as a file on the server's disk without verifying it lies inside the upload directory. A registered user can store a crafted media path with a post and cause the publishing worker to read an arbitrary file and send it as an attachment to a Discord server the user controls. The same unconfined reads are reachable through two further routes, including file existence checks and backend memory exhaustion; self-registration is open by default.
