CVE-2026-87114
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk9th percentile - higher than 9% of all known CVEs
Summary
In kube-compare, when processing a 'container://' reference path, the tool incorrectly executes an untrusted container image's entrypoint instead of merely extracting data from a stopped container. A remote attacker can achieve arbitrary code execution on the operator's workstation. If the Docker daemon requires elevated privileges, the untrusted code may execute with root-mediated daemon privileges.
Risk Assessment
Risk of operator workstation compromise by a remote attacker, potentially leading to data theft, malware installation, or further attacks on infrastructure.
Recommendation
Update kube-compare to a patched version. Restrict use of 'container://' references to trusted images and consider running the tool in a least-privilege environment.

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.

Original NVD description (English source)
A flaw was found in kube-compare. When processing a 'container://' reference path, the tool incorrectly executes an untrusted container image's entrypoint instead of merely extracting data from a stopped container. This allows a remote attacker to achieve arbitrary code execution on the operator's workstation. If the Docker daemon requires elevated privileges, the untrusted code may execute with root-mediated daemon privileges, posing a significant security risk.
