Denial of Service

Denial of service in MongoDB Server 7.0, 8.0, and 8.2 allows authenticated remote attackers to crash the database by inserting documents that trigger updates to a maliciously created '2dsphere_bucket' or 'queryable_encrypted_range' index on a non-timeseries bucket collection. The flaw stems from a reachable assertion (CWE-617) and is reported by MongoDB itself with a vendor patch available; no public exploit identified at time of analysis.

Broken access control in Arcane's GitOps backend (versions <= 1.18.1) allows any authenticated low-privilege user to exfiltrate plaintext Git credentials (PATs/SSH keys) stored for source-of-truth repositories. Eight of nine /api/customize/git-repositories endpoints omit the checkAdmin() gate, letting a 'user' role attacker repoint a repository URL to an attacker-controlled host and trigger a /test or /branches call that transmits the decrypted token via HTTP Basic auth. No public exploit identified at time of analysis, but the GHSA advisory documents a complete attack chain and a patched release (1.19.0) is available.

Prototype pollution in the npm package form-data-objectizer (<= 1.0.0) lets unauthenticated remote attackers mutate Object.prototype by submitting a single HTTP form field whose name uses bracket notation such as __proto__[polluted] or constructor[prototype][polluted]. The defect lives in treatInitial/treatSecond inside index.cjs, where an 'in' check walks the prototype chain and lets the parser write to inherited properties. CVSS is 8.2 (High) with Integrity:High; publicly available exploit code exists (working PoC published in the GHSA advisory), but there is no public exploit identified as being used in attacks and no CISA KEV listing.

Denial of service in GnuTLS affects the Datagram Transport Layer Security (DTLS) packet reordering logic, where the comparator function fails to correctly handle packets with duplicate sequence numbers. Remote unauthenticated attackers can send specially crafted DTLS packet sequences to trigger unstable ordering or undefined behavior, causing service disruption. No public exploit identified at time of analysis, and the issue is rated CVSS 7.5 (High) for availability impact only.

Denial of service in M-Files Server versions prior to 26.5.16015.0, 26.2 LTS, and 25.8 LTS SR3 allows an authenticated remote attacker to crash the MFserver process, disrupting document management services for all connected users. The flaw is reachable over the network with low privileges and no user interaction, but has no impact on confidentiality or integrity. No public exploit identified at time of analysis, and the issue is not present in CISA KEV.

Mattermost Desktop App can be repeatedly crashed by malicious server administrators through JavaScript URL injection in pop-up windows. Attackers controlling a Mattermost server can force connected desktop clients to become unusable by exploiting improper URL validation, requiring user interaction (connecting to the malicious server). No public exploit code identified at time of analysis, though the attack method is trivial to implement given the disclosed details.

Mattermost Desktop App can be crashed remotely by malicious server administrators or plugin developers exploiting insufficient isolation of server-rendered content. Authenticated attackers with low-privilege server access who can control rendered content (via compromised server, malicious plugin, or modified server responses) can invoke window.close() to terminate the desktop client, causing a client-side denial of service. EPSS data not available; no public exploit code identified at time of analysis. CVSS 3.5 (Low severity) reflects limited impact scope - disruption to individual user sessions rather than system-wide compromise.

In tinyMQTT commit 6226ade15bd4f97be2d196352e64dd10937c1962 (2024-02-18), the broker mishandles protocol violations during CONNECT packet parsing. When receiving a CONNECT packet with a zero-length Client ID while CleanSession is set to 0, the broker correctly replies with a CONNACK return code 0x02 (Identifier Rejected) but fails to explicitly close the TCP connection. Since the surrounding connection teardown logic is not guaranteed to execute, each such invalid CONNECT attempt leaves the underlying socket open. Repeated attempts cause server-side resource exhaustion due to accumulating file descriptors and memory usage, potentially resulting in denial of service.

No authentication required; exploitation requires only local file access and media playback.

Unbounded memory allocation and CPU exhaustion in OpenTelemetry Java SDK's baggage propagation allows remote unauthenticated attackers to degrade or deny service by sending oversized baggage headers. Affected components - W3CBaggagePropagator, JaegerPropagator, and OtTracePropagator - all lacked enforcement of the W3C Baggage specification's recommended size and entry limits, causing character-by-character parsing of arbitrarily large inputs. A distinctive amplification risk exists: baggage is automatically re-injected into all outgoing requests, meaning a single malicious inbound payload can fan out DoS effects to downstream services that never directly received the original request. No public exploit identified at time of analysis, and the CVE is not listed in CISA KEV.

Matrix Synapse homeserver versions prior to 1.152.1 allow authenticated local users to trigger CPU starvation that denies service to other users by exploiting unbounded lock timeout intervals in the WorkerLock implementation. Synapse deployments that do not trust all local users face service availability risk from malicious authenticated accounts. Vendor-released patch available in version 1.152.1 (GitHub commit 3f58bc50dfba5768ee43ce48c5e74c25ba0b078a confirms fix). No public exploit identified at time of analysis, though the attack mechanism is straightforward for any authenticated user.

Denial of service in GitLab Community and Enterprise Edition versions 18.5 through 18.11.2 allows unauthenticated remote attackers to disrupt service availability by sending specially crafted payloads to certain API endpoints. The flaw maps to CWE-1284 (improper validation of specified quantity in input) and has been patched in 18.9.7, 18.10.6, and 18.11.3. No public exploit identified at time of analysis and EPSS probability is very low (0.03%, 9th percentile), but the SSVC framework flags the attack as automatable with partial technical impact.

Infinite loop denial-of-service in OpenStack Ironic's image handling allows low-privileged authenticated attackers to exhaust conductor resources by supplying file:///dev/zero as an image URL, triggering unbounded checksum calculations that never terminate. All Ironic versions from 0 through 35.x prior to commit a3f6d73 are affected. No public exploit independently confirmed but SSVC data indicates proof-of-concept exists; EPSS sits at 0.01% (2nd percentile), consistent with low widespread exploitation likelihood despite the poc signal.

{ isRaw: true }]` tuple, which is passed directly into Knex's `db.connection.raw()` without sanitization. Affected versions are @strapi/content-type-builder <=5.33.1 (v5) and @strapi/plugin-content-type-builder <=4.26.0 (v4), with impact ranging from arbitrary file read and denial of service to remote code execution on database engines that permit external program execution. No public exploit identified at time of analysis; EPSS is low at 0.13% and CISA SSVC notes exploitation status of 'none', though vendor-confirmed remediation is available.

Uncontrolled resource consumption in Grafana OSS allows authenticated low-privilege users to trigger an out-of-memory (OOM) crash by exploiting the $__timeGroup macro against a configured SQL datasource. The attack is slow by nature - requiring upwards of 30 minutes to exhaust server memory - and affects Grafana OSS versions spanning from 8.0.0 through 13.0.1. Grafana reported this vulnerability directly, a vendor patch is available across all affected release branches, and no public exploit code or active exploitation has been identified at time of analysis.

Unbounded memory allocation in Grafana OSS's plugin resources endpoint allows any authenticated low-privileged user to trigger an out-of-memory condition by sending a sufficiently large HTTP request body, resulting in denial of service against the Grafana instance. Affected versions span a wide range from 6.7.0 through 13.0.1, with vendor-released security patches available across all supported branches. No public exploit exists and CISA has not added this to the KEV catalog; the EPSS score of 0.04% (12th percentile) reflects very low observed exploitation probability.
