CVE Database

A security issue was discovered in MongoDB mongos (the sharded cluster router) where an authenticated user with readWrite privileges could crash the mongos process by crafting a specially formed aggregation pipeline. The issue leverages an internal aggregation stage that lacks proper authorization checks despite being intended for internal use, allowing a subsequent stage to be forced to execute on the router under conditions it was not designed to handle. This results in an unhandled fatal error that causes the mongos process to immediately abort, resulting in denial of service for all clients routed through the affected mongos instance.

MongoDB Server's collection validation feature may not properly handle certain expressions stored in a validator. In some cases, this can cause the server process to stop running when a document is later inserted. The behavior can occur for authenticated users with write access.

An issue in MongoDB Server's aggregation framework can cause certain constant values to be handled incorrectly during internal query rewriting. Under certain conditions, an authenticated user with read access may receive field values in aggregation output that the query did not intend to return.

Plane is an open-source project management tool. Prior to 1.4.0, multiple issue-listing endpoints, including unauthenticated public deploy boards handled by IssueListSpaceEndpoint in apps/api/plane/space/views/issue.py, pass the user-controlled order_by parameter through order_issue_queryset in apps/api/plane/utils/order_queryset.py to Django's order_by without allowlist validation. An attacker can use double-underscore relationship traversal to reference arbitrary related model fields, revealing database schema details through errors and potentially disclosing field values through differential ordering. This issue is fixed in version 1.4.0.

[This CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] 1) XSA-437 (CVE-2023-34321) addressed issues with overflows in calculations involved in guests flushing caches through GNTTABOP_cache_flush. Unfortunately the fix there introduced a calculation which may underflow, resulting in a loop which would - at least on 64-bit Arm - take excessively long, and which would likely eventually crash the hypervisor. This is CVE-2026-102699. 2) GNTTABOP_cache_flush may be issued on memory mapped from another domain using the grant table interface. However there was no restriction to disallow the use of invalidate-without-clean against read-only grant mappings, which may corrupt the granted memory. This is CVE-2026-102702.

With its original introduction, GNTTAB_cache_flush was made available uniformly. XSA-232 (CVE-2017-14318) then covered an omitted NULL pointer check, yet the addition of that check failed to adjust the subsequent error path. That error path fails to drop a page reference in case the specified page is owned by a special system domain (DOM_IO and DOM_COW are system domains which can have memory pages assigned to them.)

Insufficient session randomness vulnerability in the listed NETGEAR Extender models allows a network-adjacent attacker having network access (such as WiFi credentials) to predict valid session identifiers and hijack an authenticated administrator session on the web management portal.

A vulnerability was found in girishsaraf Online-Appointment-Booking-System up to f427b4757128ca253d33d0cc4e87bbb9c999a4d5. Affected by this vulnerability is an unknown functionality of the file Admin/getclinic.php of the component AJAX Endpoint. The manipulation of the argument city/cid results in sql injection. The attack can be executed remotely. The exploit has been made public and could be used. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. The project was informed of the problem early through an issue report but has not responded yet.

SFTPGo is an open source, event-driven file transfer solution. From 2.5.0 until 2.7.6, an authenticated user with copy permission can copy a source file denied by denied_patterns or outside allowed_patterns to an allowed destination name because file-pattern filters are evaluated only on the destination. The user can then read the denied file contents. Recursive directory copies can reproduce restricted contents under an allowed path, and the hide policy is bypassed because files that appear missing to stat and directory listings can still be copied. Home-directory boundaries, virtual-folder layout, per-directory permissions, access to other accounts, and administrative authorization remain enforced. This issue is fixed in 2.7.6.

Wazuh from 4.1.1 before 4.14.8 contains a path traversal vulnerability in the get_list_file helper that allows malicious cluster workers to read arbitrary files via unvalidated filename values. Attackers holding the cluster key can send DistributedAPI requests with traversal filenames to read client.keys, ossec.conf with the cluster key, and other wazuh-readable files.

Wazuh from 4.0.0 before 4.14.8 contains an information disclosure vulnerability that allows low-privileged users with agent:read to retrieve the plaintext authd.pass enrollment password via the unmasked agent configuration endpoint. Attackers holding the default readonly role can request the auth component configuration for pseudo-agent ID 000 to obtain the secret and enroll rogue agents against the manager.
