CVE Vulnerability Catalog

Sending a "NOOP (((...)))" command with 4000 parentheses increases memory usage by about 1 MB. Longer commands cause client disconnection. An attacker can keep this memory allocated by not sending the line feed (LF) character.

Dovecot provides a script for attachment to text conversion that unsafely handles zip-style attachments. An attacker can use specially crafted OOXML documents to cause unintended files on the system to be indexed and subsequently end up in FTS indexes. Do not use the provided script; instead, use something else like FTS tika. No publicly available exploits are known.

When sending invalid base64 SASL data, the login process is disconnected from the auth server, causing all active authentication sessions to fail. Invalid BASE64 data can be used to DoS a vulnerable server to break concurrent logins. No publicly available exploits are known.

A flaw was found in firewalld where a local unprivileged user can exploit mis-authorization of two D-Bus setters: setZoneSettings2 and setPolicySettings. This allows modification of the runtime firewall state without proper authentication.

The Grafana MSSQL data source plugin contains a logic flaw that allows a low-privileged user (Viewer) to bypass API restrictions and trigger a catastrophic Out-Of-Memory (OOM) memory exhaustion, crashing the host container.

A flaw was found in p11-kit where a remote attacker could call the C_DeriveKey function on a remote token with specific IBM kyber or IBM btc derive mechanism parameters set to NULL. This could lead to the RPC-client attempting to return an uninitialized value, potentially resulting in a NULL dereference or undefined behavior.

A vulnerability has been discovered in Grafana OSS that allows an authorization bypass in the provisioning contact points API. Users with Editor role can modify protected webhook URLs without the required alert.notifications.receivers.protected:write permission.

A flaw was found in libssh. A remote attacker, by controlling client configuration files or known_hosts files, could craft specific hostnames that when processed by the `match_pattern()` function can lead to inefficient regular expression backtracking. This can cause timeouts and resource exhaustion, resulting in a Denial of Service (DoS) for the client.

A malicious SCP server can send unexpected paths that could make the client application override local files outside of the working directory. This could be misused to create malicious executable or configuration files and make the user execute them. This is the same issue as in OpenSSH, tracked as CVE-2019-6111.

InvenTree is an Open Source Inventory Management System. Prior to version 1.2.6, a path traversal vulnerability in the report template engine allows a staff-level user to read arbitrary files from the server filesystem via crafted template tags. Affected functions: `encode_svg_image()`, `asset()`, and `uploaded_image()` in `src/backend/InvenTree/report/templatetags/report.py`. This requires staff access (to upload / edit templates with maliciously crafted tags). If the InvenTree installation is configured with high access privileges on the host system, this path traversal may allow file access outside of the InvenTree source directory. This issue is patched in version 1.2.6, and 1.3.0 (or above). Users should update to the patched versions. No known workarounds are available.

Mattermost Plugins versions <=11.4, 11.0.4, 11.1.3, 11.3.2, and 10.11.11.0 fail to validate incoming request size, allowing an authenticated attacker to disrupt service via the webhook endpoint.

A flaw was found in polkit. A local user can exploit this by providing a specially crafted, excessively long input to the `polkit-agent-helper-1` setuid binary via standard input (stdin). This unbounded input can lead to an out-of-memory (OOM) condition, resulting in a Denial of Service (DoS) for the system.

A flaw was found in GIMP, which is a heap buffer over-read in the PCX file loader due to an off-by-one error. A remote attacker could exploit this by convincing a user to open a specially crafted PCX image.

A NULL pointer dereference vulnerability was found in the Linux kernel's icmp_tag_validation() function. When hardened PMTU mode is enabled (ip_no_pmtu_disc=3) and an ICMP Fragmentation Needed packet with an inner IP header containing an unregistered protocol number is received, a kernel panic occurs in softirq context.

A vulnerability in NATS-Server before versions 2.11.15 and 2.12.6 allows a malicious client to cause unbounded memory usage before authentication via WebSockets connection. The attack requires sending a corresponding amount of data and is a milder variant of CVE-2026-27571.

Domoticz versions prior to 2026.1 contain a stored cross-site scripting vulnerability in the Add Hardware and rename device functionality. An authenticated administrator can inject malicious code via crafted names containing script or HTML markup, which is stored and executed in the browsers of other users viewing the affected page.

The Grid plugin for WordPress (up to version 2.8.0) contains a stored Cross-site Scripting (XSS) vulnerability due to improper neutralization of input during web page generation. An attacker can inject malicious scripts that execute in the victim's browser.

A vulnerability in the web-based management interface of Cisco Catalyst SD-WAN Manager allows an authenticated, remote attacker to perform a cross-site scripting (XSS) attack against a user of the interface. This is due to insufficient input validation.

A vulnerability in the bootloader of Cisco IOS XE Software for Cisco Catalyst 9200, ESS9300, IE9310, IE9320, IE3500, and IE3505 switches could allow an authenticated local attacker with level-15 privileges or an unauthenticated attacker with physical access to execute arbitrary code at boot time and break the chain of trust. This is due to insufficient validation of software at boot time, enabling manipulation of loaded binaries to bypass integrity checks.

W jądrze systemu Linux zidentyfikowano podatność, która pozwala na błędne usunięcie gniazda z kolejki odbiorczej przez zbieranie śmieci (GC) w wyniku wywołania MSG_PEEK. Problem ten występuje w sytuacji, gdy gniazdo jest zamykane podczas sprawdzania jego stanu przez GC, co prowadzi do nieprawidłowego wniosku o martwym gnieździe.
