tomcat: timing attack in Realm implementation

The Realm implementations in Apache Tomcat versions 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 did not process the supplied password if the supplied user name did not exist. This made a timing attack possible to determine valid user names. Note that the default configuration includes the LockOutRealm which makes exploitation of this vulnerability harder.

CVE-2021-35477

kernel: BPF program can obtain sensitive information from kernel memory via a speculative store bypass side-channel attack because the technique used by the BPF verifier to manage speculation is unreliable

In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation does not necessarily occur before a store operation that has an attacker-controlled value.

kernel: BPF program can obtain sensitive information from kernel memory via a speculative store bypass side-channel attack because of the possibility of uninitialized memory locations on the BPF stack

In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects the possibility of uninitialized memory locations on the BPF stack.

CVE-2020-27170

kernel: Speculation on pointer arithmetic against bpf_context pointer

An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-f232326f6966. This affects pointer types that do not define a ptr_limit.

CVE-2026-56098

Rubygem-katello: improper authorization logic allows resource enumeration

A flaw was found in rubygem-katello. The RegistryProxiesController in Katello contains an authorization bypass vulnerability due to an execution fall-through in the registry_authorize filter. While the application identifies unauthorized requests and triggers an error response via the unauthorized method, it fails to halt the execution of the current code path (missing return statement). This failure in the control flow allows the application to proceed into subsequent business logic and database validation filters. Consequently, the application reveals its internal state through differential responses, allowing an unprivileged attacker to enumerate valid Users, Organizations, and Products across the entire instance.

Ghost: Password Hash Ordering Disclosure in Ghost Admin API

Ghost is a Node.js content management system. From 0.7.2 until 6.64.0, any staff-level user was able to determine the relative ordering of other staff users' hashed passwords. This does not directly disclose password hashes, and does not provide a practical path to recovering a password. This issue is fixed in version 6.64.0.

Ghost: Invite Token Disclosure in Ghost Admin API

Ghost is a Node.js content management system. From 4.39.0 until 6.64.0, staff users with permission to view staff invites were able to discover the secret token of pending invites, including invites for roles with higher privileges than their own. This could allow a staff user to escalate their privileges by accepting a pending invite. This issue is fixed in version 6.64.0.

Ghost 5.42.2 before 6.58.0 contains an information disclosure vulnerability in the Admin API bulk post and page edit and delete endpoints, which accept filters on restricted fields such as authors.password, because of an incomplete fix for CVE-2026-70590. Staff-level attackers can infer other staff users' password hashes from which filters match and perform offline password-guessing attacks against them.

Zammad: Missing rate limiting allows password brute-forcing during two-factor login

Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, the two-factor login step let an attacker try unlimited password guesses for any account without triggering Zammad's normal lockout or rate limiting. The response also revealed whether a guess was correct, even before two-factor authentication was checked. This made it possible to brute-force weak or reused passwords. This issue is fixed in version 7.1.2.
