CVE Vulnerability Catalog

A heap-based buffer overflow was found in dnsmasq. When DNSSEC validation and query logging are both enabled, logging of DS or DNSKEY replies containing unsupported algorithm or digest types can cause dnsmasq to write past the end of an internal logging buffer. A remote attacker able to supply such a DNS response may crash the dnsmasq process, resulting in denial of service.

The fix for CVE-2026-2443 was regressed by a subsequent rework commit that replaced specific overflow checks with a general signed comparison. When a client sends a Range request with a suffix length exceeding the content size, the resulting negative start value is not properly clamped, leading to malformed HTTP 206 responses and log flooding.

A path traversal vulnerability exists in version 3.14.0 of the Keras library, related to the `DiskIOStore.make` method. The issue arises from improper handling of user-provided layer names, allowing unauthorized file system operations.

Akaunting version 3.1.21 contains an authenticated stored cross-site scripting vulnerability in the document timeline shown on invoice and bill detail pages. An authenticated user can store HTML/JavaScript in their profile name.

Akaunting 3.1.21 contains an authenticated stored cross-site scripting vulnerability in the reusable delete confirmation flow. A user with permission to create or modify records, such as Items, can store HTML/JavaScript in the record name.

IBM TRIRIGA Application Platform versions 5.0.2 through 5.0.3 are vulnerable to cross-site scripting (XSS). An authenticated user can embed arbitrary JavaScript code in the Web UI, potentially leading to credential disclosure within a trusted session.

IBM Engineering Workflow Management versions 7.0.2 through 7.0.2 Interim Fix 035, 7.0.3 through 7.0.3 Interim Fix 017, and 7.1 through 7.1 Interim Fix 004 are vulnerable to HTTP header injection due to improper validation of input in the HOST headers. This could allow an attacker to conduct various attacks against the vulnerable system, including cross-site scripting, cache poisoning, or session hijacking.

A vulnerability in IBM Db2 on Cloud Pak for Data and Db2 Warehouse on Cloud Pak for Data versions 4.8, 5.0, 5.1, 5.2, and 5.3 allows an authenticated user to bypass client-side validation and manipulate input data using man-in-the-middle techniques.

Mattermost versions 11.7.x <= 11.7.0, 11.6.x <= 11.6.2, 11.5.x <= 11.5.5, and 10.11.x <= 10.11.17 fail to invalidate cached authentication state for active WebSocket connections during global session revocation. This allows a user with an existing WebSocket connection to remain authenticated and continue receiving real-time events until the cached session expires or the client reconnects.

The vulnerability arises when the system fails to properly validate the 'email' field during the authentication process, allowing unverified or fake email addresses to be accepted. This lack of validation enables the creation of user accounts with fake email addresses, facilitating the mass creation of fraudulent accounts.

Mattermost versions 11.7.x <= 11.7.0, 11.6.x <= 11.6.2, 11.5.x <= 11.5.5, and 10.11.x <= 10.11.17 fail to authenticate Atlassian Connect installed callbacks, allowing a remote unauthenticated attacker to inject a rogue sharedSecret and disrupt the Jira integration.

Mattermost versions 11.7.x <= 11.7.0, 11.6.x <= 11.6.2, 11.5.x <= 11.5.5, and 10.11.x <= 10.11.17 fail to validate channel ownership of an existing subscription before applying edits. This allows an authenticated attacker to hijack subscriptions from channels they have no access to via a crafted PUT request to the subscription edit endpoint.

Mattermost versions 11.7.x <= 11.7.0, 11.6.x <= 11.6.2, 11.5.x <= 11.5.5, and 10.11.x <= 10.11.17 fail to enforce administrator authorization on the {{setDefaultInstance}} call within the {{/gitlab connect}} command handler, allowing any authenticated user to overwrite the global default GitLab instance configuration via the {{/gitlab connect <instance-name>}} slash command.

AIL did not restrict repeated failed attempts to verify a two-factor authentication (OTP) code. An attacker who reached the 2FA verification step could submit an unlimited number of OTP guesses, potentially leading to unauthorized account access.

A vulnerability in the Tempo and Loki data source plugins allows a user with Viewer permissions to reach unintended backend endpoints via specially crafted requests. This can expose data source credentials, leak internal responses, or trigger administrative actions on the configured backend.

An XSS vulnerability in IBM Engineering Workflow Management allows an authenticated user to embed arbitrary JavaScript code in the Web UI, potentially leading to credential disclosure within a trusted session.

A vulnerability in IBM Db2 on Cloud Pak for Data and Db2 Warehouse on Cloud Pak for Data versions 4.8, 5.0, 5.1, 5.2, 5.3 could allow a privileged user to perform operations and obtain sensitive information outside of their authority due to improper token validation.

A vulnerability in IBM Db2 on Cloud Pak for Data and Db2 Warehouse on Cloud Pak for Data versions 4.8, 5.0, 5.1, 5.2, 5.3 allows an authenticated user to cause a denial of service when creating new databases due to improper resource allocation.

An unvalidated redirect was contained in Venueless' social login functionality and could be exploited for phishing using trusted domains.

Untrusted user data was passed verbatim to Excel exports for administrators. This allowed formula injection which can be used to compromise the environment of the user loading the file or other data in the file.
