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.
Authenticated users can crash MongoDB Server by chaining specific server-side JavaScript operations ($_internalJsEmit or mapreduce map functions) with subsequent JavaScript engine invocations ($where, $function, mapreduce reduce stages), triggering a use-after-free condition. Affects MongoDB Server 7.0 (prior to 7.0.34), 8.0 (prior to 8.0.23), 8.2 (prior to 8.2.9), and 8.3 (prior to 8.3.2). Vendor-released patches available for all affected branches. No public exploit identified at time of analysis; EPSS score of 0.05% (16th percentile) suggests low observed exploitation probability despite 7.7 CVSS score. The CWE-416 use-after-free root cause requires precise sequencing of JavaScript operations, limiting exploitability.
Authenticated attackers can exhaust MongoDB Server memory using malicious bitwise match expressions ($bitsAllSet, $bitsAnySet, $bitsAllClear, $bitsAnyClear), leading to out-of-memory denial of service. Affects MongoDB Server 7.0 prior to 7.0.34, 8.0 prior to 8.0.23, 8.2 prior to 8.2.9, and 8.3 prior to 8.3.2. Vendor-released patches are available across all affected major versions. EPSS score of 0.04% (12th percentile) indicates low observed exploitation probability in the wild, and no public exploit code has been identified at time of analysis.
Out-of-bounds memory write in MongoDB Server's time-series collection feature enables arbitrary code execution by authenticated users with database write privileges. Affects all active release branches (5.0 through 8.3) when exploiting field-name-to-index mapping inconsistencies in the time-series bucket catalog. EPSS score of 0.06% (20th percentile) suggests low widespread exploitation probability despite high CVSS 8.7, but requires authentication and database privileges, limiting attack surface to insider threats or compromised application credentials. No public exploit code or CISA KEV listing identified at time of analysis.
Command injection in MongoDB Ops Manager (all 7.0 versions and 8.0.22 and prior) lets an administrative user with webhook-configuration rights achieve arbitrary command execution by embedding malicious FreeMarker template syntax in a webhook and then triggering it. The flaw is vendor-reported (MongoDB) with a patch in 8.0.23; there is no public exploit identified at time of analysis and EPSS is very low (0.05%), consistent with SSVC's 'exploitation: none' rating despite the total technical impact.
MongoDB Server 8.2 before version 8.2.7 crashes when an authenticated user supplies an empty pipeline to $rankFusion or $scoreFusion aggregation operators on a view. The server fails to validate that the pipeline array is non-empty before accessing its first element during view resolution, resulting in a null pointer dereference that terminates the mongod process. This denial-of-service condition requires database authentication but can be triggered remotely via aggregation queries.
Heap buffer overflow in MongoDB C Driver's Cyrus SASL integration allows local attackers to achieve code execution before authentication by providing a maliciously crafted username in a MongoDB URI with GSSAPI authentication. The vulnerability triggers during username canonicalization via unsafe string copying, requiring no privileges or user interaction. Exploitable against any application using the affected driver that processes untrusted MongoDB connection strings. No active exploitation confirmed (not in CISA KEV). EPSS data not provided. Vendor has acknowledged the issue via JIRA tracking (CDRIVER-6134).
MongoDB Server sharded clusters are vulnerable to use-after-free memory corruption when authenticated users with read permissions execute malicious $lookup or $graphLookup aggregation pipeline operations. An attacker can exploit this vulnerability to achieve high-impact outcomes including information disclosure, data manipulation, and denial of service. No patch is currently available for this vulnerability.
An authenticated user with read-only role can extract limited amounts of uninitialized stack memory through specially crafted issuances of the filemd5 command in MongoDB Server. This information disclosure vulnerability affects MongoDB Server versions 8.2 prior to 8.2.6, 8.0 prior to 8.0.20, and 7.0 prior to 7.0.31. An attacker with valid database read credentials can exploit this to leak sensitive data from process memory without requiring elevated privileges or user interaction.
Prototype pollution in MongoDB Compass's CSV import parsing logic creates a '1-click' command execution path across versions 1.36.x through 1.49.5. A crafted CSV file can pollute JavaScript object prototypes during the import workflow, causing untrusted file paths to reach Electron's shell.openExternal() API and be executed by the operating system's default handler. No public exploit code has been identified and this CVE is absent from CISA KEV, but the passive user-interaction requirement - simply importing a CSV as part of routine database work - makes targeted social engineering a credible delivery vector in data-heavy environments.
The legacy GridFS API in the MongoDB C Driver fails to validate file metadata fields retrieved from the database, enabling crafted documents stored in a GridFS collection to trigger either a division-by-zero crash (denial of service) or an out-of-bounds read that exposes process memory contents to the caller. Versions in the 1.x branch before 1.30.8 and 2.x branch before 2.2.4 are affected per EUVD-2026-31132. The CVSS 4.0 score of 6.0 accurately reflects a constrained attack path requiring low-privilege database access and a pre-positioned malicious document (AT:P), with no public exploit identified at time of analysis.
Stack exhaustion in MongoDB PHP driver allows remote denial of service when processing deeply nested BSON documents from untrusted sources. Unauthenticated attackers can crash applications by sending maliciously crafted BSON payloads with excessive nesting levels, affecting all versions of the PHP driver that parse BSON without depth limits. The vulnerability requires high attack complexity but results in complete availability loss.
Denial of service in MongoDB Server v7.0 through v8.3 allows authenticated users with aggregation permissions to exhaust CPU resources via densely populated character masks in $trim, $ltrim, and $rtrim aggregation operators. An attacker can pin CPU utilization at 100% for extended periods by crafting malicious aggregation queries with large input strings and computationally expensive mask patterns. No public exploit code or active exploitation has been reported at time of analysis.
Use-after-free in MongoDB Server's Field-Level Encryption query analysis component allows authenticated remote attackers with control over FLE query structure to cause information disclosure and denial of service. The vulnerability affects mongocryptd and crypt_shared in versions 7.0 prior to 7.0.34, 8.0 prior to 8.0.23, 8.2 prior to 8.2.9, and 8.3 prior to 8.3.2. No public exploit code identified at time of analysis.
MongoDB Server fails to fully redact user data in local server log messages when schema validation is enabled and an update or insert operation violates the collection schema, allowing authenticated administrators to access sensitive information through log inspection. This information disclosure affects MongoDB Server 7.0 prior to 7.0.34, 8.0 prior to 8.0.23, 8.2 prior to 8.2.9, and 8.3 prior to 8.3.2. The vulnerability requires high-privilege administrative access and has a low CVSS score of 2.7, indicating limited real-world impact despite confirmed patch availability.
MongoDB C Driver bson_validate function returns early on specific inputs and incorrectly reports successful validation, allowing malformed or invalid UTF-8 sequences in BSON data to bypass validation checks. This affects MongoDB C Driver versions prior to 1.30.5, 2.0.0, and 2.0.1, and impacts applications that depend on this validation function to process untrusted BSON data. Authenticated remote attackers can exploit this to inject invalid BSON data, potentially causing integrity issues in downstream processing; EPSS 0.48 indicates this is a moderate-priority issue that warrants patching but is not among the highest-risk vulnerabilities.
Crash-inducing denial-of-service in the MongoDB C Driver (all versions before 2.2.3) allows a network-privileged adversary - either a compromised third-party cloud server the application trusts or a man-in-the-middle attacker on the network path - to crash the consuming application by delivering a malformed HTTP response. The vulnerability carries a CVSS 4.0 score of 2.0 due to high attack complexity, prerequisite network positioning, and impact limited strictly to low availability on the vulnerable system. No public exploit code exists and EPSS probability sits at 0.03% (8th percentile), indicating negligible observed exploitation activity at time of analysis.
Memory corruption in MongoDB Server's slot-based execution engine can be triggered by authenticated users with write privileges through malicious $lookup aggregation queries that cause hash table spillover to disk. Successful exploitation enables denial of service and potential information disclosure, though a patch is not currently available. The attack requires network access and specific query construction, limiting the practical exploit window.
