CVE-2017-15088
CriticalSummary
The MIT Kerberos 5 (krb5) library up to version 1.15.2 mishandles Distinguished Name (DN) fields, allowing remote attackers to execute arbitrary code or cause application crashes via buffer overflow.
Risk Assessment
Attackers may exploit this vulnerability to execute code remotely or disrupt system operations, leading to serious security implications for the organization.
Recommendation
It is recommended to upgrade to the latest version of MIT Kerberos to mitigate this vulnerability and to monitor the use of functions related to X.509 data processing.

A vulnerability was detected in Unitree Robotics Unitree Go2 up to version 1.1.11.4. The set_volume function in gpt_thread.py of the chat_go component mishandles the Value argument, leading to OS command injection. The attack can be launched remotely, and upgrading to version 1.1.11.5 resolves the issue.
- 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.

- CVE-2026-111402Critical
The WordPress plugin Newsletters (newsletters-lite) up to version 4.18.1 is vulnerable to SQL injection due to improper neutralization of special elements in SQL commands. This could allow an attacker to execute arbitrary SQL queries.
- CVE-2026-110956Critical
The asVereinbase WordPress plugin before version 1.1.8 does not require a valid password or a genuine second factor before authenticating a user, treating an empty stored value as a match. This allows an unauthenticated attacker to log in as any user, including an administrator.
Original NVD description (English source)
plugins/preauth/pkinit/pkinit_crypto_openssl.c in MIT Kerberos 5 (aka krb5) through 1.15.2 mishandles Distinguished Name (DN) fields, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) in situations involving untrusted X.509 data, related to the get_matching_data and X509_NAME_oneline_ex functions. NOTE: this has security relevance only in use cases outside of the MIT Kerberos distribution, e.g., the use of get_matching_data in KDC certauth plugin code that is specific to Red Hat.
