MongoDB Server's bundled MozJS (SpiderMonkey) scripting engine unconditionally registers a module loading hook that permits JavaScript code - executing inside aggregation pipeline stages - to read arbitrary files from the host filesystem using the mongod process's OS-level privileges. Any authenticated database user with permission to run JavaScript-enabled aggregation stages can craft pipeline commands to exfiltrate sensitive host files such as private keys, configuration files, or application secrets, bypassing MongoDB's own role-based access controls. No public exploit code or CISA KEV listing exists at time of analysis, but low attack complexity and a default-enabled attack surface make this a meaningful threat in any deployment with untrusted or broadly-credentialed users.
Out-of-bounds heap read in MongoDB Server's BSON CodeWScope element accessors lets an authenticated user disclose adjacent heap memory or crash the server (denial of service) by submitting a crafted aggregation pipeline. The exploit path abuses malformed BSONColumn (columnar/compressed BSON) data whose CodeWScope element bypasses the normal wire-level BSON validation, so an unchecked size field is trusted during decompression. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; the CVSS 4.0 base score is 7.1, driven mainly by high availability impact.
Denial of service in MongoDB's aggregation framework allows an authenticated database user with write access to crash the mongod process by triggering a specific data type conversion operation that consumes disproportionate memory, causing the operating system's out-of-memory killer to terminate the process under memory pressure. Affected are MongoDB server deployments where low-privileged users can run aggregation queries; the CVSS 4.0 score is 7.1 with high availability impact and no confidentiality or integrity impact. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Denial of service in MongoDB Server (mongod) allows an authenticated user with aggregation privileges to force the operating system to terminate the mongod process under memory pressure by abusing the $rankFusion and $scoreFusion hybrid-search aggregation stages. The flaw sits in the server's error-handling path and requires only the ability to run aggregation queries, causing an OOM-triggered crash of the database instance. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Excessive CPU consumption in MongoDB Server's awaitable hello command exhaust mode allows unauthenticated remote clients to degrade server availability without any credentials. A specific parameter combination triggers a server-side response loop that bypasses normal throttling mechanisms, meaning even a small number of malicious connections can measurably impair database availability. No active exploitation has been confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis; the CVSS 4.0 score of 6.9 with VA:L reflects a real but bounded availability impact.
MongoDB's mongod daemon can be crashed by any authenticated user holding only read-only privileges, dropping database service for every connected client until an operator restarts the process. The root cause is CWE-617 (Reachable Assertion) inside the aggregation framework's engine selection logic - a state the codebase assumed unreachable that a crafted combination of aggregation options can actually trigger. No public exploit code has been identified at time of analysis and no CISA KEV listing exists, but the PR:L attack vector makes this a reliable insider-threat and post-compromise availability weapon against any network-reachable MongoDB deployment.
Memory corruption in MongoDB standalone mongod servers running with compute mode enabled allows remote attackers to crash the process (denial of service) or trigger undefined behavior by supplying maliciously crafted BSON data that is mishandled during aggregation pipeline processing (CWE-122 heap overflow). Only servers explicitly started in the non-default compute mode are affected. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV; the vendor rates it CVSS 4.0 9.2 (Critical) despite high attack complexity and a required precondition.
Denial of service in MongoDB's mongod server allows any authenticated user holding only read privileges to crash the database by submitting aggregation pipeline expressions that invoke server-side JavaScript, triggering a use-after-free (CWE-416) during document processing. The flaw affects availability only and requires valid low-privilege credentials; no public exploit identified at time of analysis and it is not listed in CISA KEV.
MongoDB Server terminates abnormally during outbound TLS handshake when a remote peer delivers a malformed OCSP response, producing a denial-of-service condition against the database process itself. OCSP stapling validation is enabled by default for all outgoing TLS connections, meaning no operator misconfiguration is required to expose this attack surface - any MongoDB server initiating TLS connections is potentially reachable. No public exploit code exists and no CISA KEV listing is present at time of analysis, but the default-enabled feature combined with the adjacent-network attack vector makes this a credible operational risk for MongoDB clusters traversing partially trusted or shared network segments.
Denial of service in MongoDB Server allows an authenticated user to exhaust CPU or trigger out-of-memory conditions by submitting a crafted Queryable Encryption 'find' payload whose unvalidated field drives an internal computation loop. The resulting resource exhaustion degrades availability for all other operations on the affected instance. No public exploit identified at time of analysis, and it is not listed in CISA KEV; the issue is tracked internally as MongoDB SERVER-127566.
MongoDB's cursor termination authorization logic fails to scope privileges to the correct database namespace, allowing an authenticated low-privilege user to terminate active cursors on databases they do not administer. Exploitation requires the attacker to hold cursor termination rights on at least one database, limiting the practical threat to malicious or compromised internal users. No public exploit has been identified at time of analysis, and this vulnerability has not been added to the CISA Known Exploited Vulnerabilities catalog.
Improper authorization in MongoDB Server allows a local attacker holding a valid trusted-CA X.509 certificate to obtain unintended database roles when PROXY protocol v2 is used over the Unix domain socket, because certificate-derived roles bypass the configured tlsCATrusts allow-list during MONGODB-X509 authentication. An attacker with local access to the proxy socket can therefore escalate to roles they were never granted, compromising confidentiality and integrity of data. Tracked via MongoDB SERVER-128387 and rated CVSS 4.0 7.2 (High); no public exploit identified at time of analysis and it is not listed in CISA KEV.
Information disclosure in MongoDB's server-side JavaScript engine allows authenticated database users to read fragments of internal server process memory. The flaw stems from improper handling of DBPointer objects during BSON serialization, causing uninitialized or adjacent memory contents to be returned to the client. Only deployments that enable server-side JavaScript are affected; no public exploit has been identified at time of analysis and it is not listed in CISA KEV.
Denial of service in MongoDB Server allows an authenticated user holding only read-only privileges to crash the mongod process by submitting an aggregation pipeline that uses the $linearFill window function with a maliciously typed sortBy expression. Because the required privilege level is minimal (any read user) and the trigger is a single crafted query over the normal database wire protocol, a low-privilege account can repeatedly terminate the database node. No public exploit has been identified at time of analysis, and the issue is not listed in CISA KEV; EPSS was not provided.
Denial of service in MongoDB allows an authenticated attacker to exhaust server CPU by submitting query operations that use deeply nested $jsonSchema validation constructs, producing a runaway CPU-bound operation that cannot be halted via standard administrative controls such as killOp. Reported by MongoDB's own CNA (SERVER-125872) and classified as inefficient algorithmic complexity (CWE-407), with no public exploit identified at time of analysis. The inability to interrupt the operation elevates this above a routine resource-consumption bug because normal recovery tooling is ineffective.
Denial of service against the MongoDB mongod process is achievable by any authenticated user holding standard read/write privileges by submitting a crafted aggregation command that exploits insufficient input validation in the bundled libmongocrypt library. An integer overflow (CWE-190) in libmongocrypt allows attacker-controlled payload values to produce an excessively large memory allocation request, causing the operating system to terminate the mongod process under an out-of-memory condition. No public exploit has been identified and this vulnerability is not listed in the CISA KEV catalog at time of analysis.
Integrity corruption in MongoDB's Queryable Encryption on sharded clusters lets an authenticated user with write access to a QE-enabled collection tamper with server-controlled encryption metadata by routing crafted write commands through the mongos router, breaking the correctness of encrypted queries. The CVSS 4.0 vector (VI:H, VC:N, VA:N) confirms this is an integrity-only issue despite the input's 'Information Disclosure' tag, which appears mislabeled. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Incorrect authorization in MongoDB's $listSessions aggregation stage allows any authenticated user to enumerate session metadata cluster-wide - a capability that should be restricted to cluster-level administrators. Exposed data includes active session identifiers, associated usernames, and activity timestamps, which in combination represent a meaningful secondary risk for session-hijacking attempts against high-value accounts. No public exploit code exists and this is not listed in CISA KEV at time of analysis; however, the low exploitation bar (any valid MongoDB account) in multi-tenant environments elevates real-world concern above the moderate CVSS score alone.
Authorization bypass in MongoDB Server allows an authenticated user holding limited read privileges to read documents from collections they are not permitted to access, exploiting a discrepancy between how the $graphLookup aggregation stage is authorized versus how it is executed when the target collection is referenced inside an existing view's pipeline definition. The flaw (CWE-863, Incorrect Authorization) yields cross-collection data disclosure with no integrity or availability impact. No public exploit was identified at time of analysis and the issue is not listed in CISA KEV; it was self-reported by MongoDB's CNA and tracked in SERVER-127357.
Authorization bypass in MongoDB Server allows an authenticated low-privileged user to read and write documents that should be shielded by role-based, query-level access controls. Because the server insufficiently validates certain client-supplied command parameters, crafted find, update, delete, and aggregate commands can sidestep the access boundaries enforced for a user's role. The flaw only manifests in non-apiStrict deployments (the default), and per the vendor CVSS 4.0 vector it yields high confidentiality and integrity impact; no public exploit has been identified at time of analysis.
Denial of service in MongoDB Server (mongod) allows an authenticated user holding only basic write privileges to crash the database process by submitting a crafted transaction command that omits some required fields. The inconsistent validation of related transaction parameters trips a fatal internal invariant (CWE-617), aborting mongod and interrupting availability for all clients. No public exploit has been identified at time of analysis, and the flaw is not listed in CISA KEV; impact is limited to availability, with no data disclosure or integrity effect.
Atlas Search integration in MongoDB's sharded topology exposes a per-user access control bypass to authenticated low-privileged users. The `$search` and `$searchMeta` aggregation pipeline stages rely on internal routing fields that are intended to be injected exclusively by the trusted mongos router during sharded query planning; due to insufficient input validation (CWE-20), an authenticated client can supply these fields directly and circumvent the access controls normally enforced per-user. No public exploit has been identified at time of analysis, and the vulnerability is not listed in CISA KEV; the CVSS 4.0 score of 6.0 reflects the combination of high confidentiality impact against a sharded-only attack surface requiring authenticated access.
Denial of service in MongoDB Server allows an authenticated database user to submit an aggregation/query expression that generates very large arrays, forcing the server to allocate oversized intermediate objects in memory and crash with an out-of-memory (OOM) error. Reported by MongoDB's own CNA and tracked in SERVER-124355, the flaw carries a CVSS 4.0 base score of 7.1 with an availability-only impact (VA:H). No public exploit identified at time of analysis, and it is not listed in CISA KEV.
Denial of service in MongoDB Server (mongod) lets any authenticated user with aggregation-pipeline privileges crash the database process by invoking the internal `$_internalIndexKey` aggregation expression against a compound wildcard index. The expression fails to handle compound wildcard index specifications, tripping an internal consistency check (assertion) that aborts the server. No public exploit identified at time of analysis, and the flaw is reported by MongoDB's own CNA as a Denial of Service issue with no confidentiality or integrity impact.
Memory disclosure and denial of service in MongoDB Server's server-side JavaScript engine allow an authenticated user with read privileges and JavaScript execution rights to read freed heap memory or crash the mongod process. The flaw is triggered during BSON-to-JavaScript array conversion when operators such as $where or $function are evaluated. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV; it was self-reported by MongoDB.
Information disclosure in MongoDB Server allows authenticated users holding the read role to obtain small amounts of uninitialized stack memory by submitting specially-crafted filemd5 commands. The flaw stems from CWE-457 (Use of Uninitialized Variable) in the filemd5 command handler, and while no public exploit has been identified at time of analysis, the low attack complexity and network reachability make it a credible insider/credential-theft risk against MongoDB databases.
Feathersjs is a framework for creating web APIs and real-time applications with TypeScript or JavaScript. From 5.0.0 to before 5.0.42, Socket.IO clients can send arbitrary JavaScript objects as the id argument to any service method (get, patch, update, remove). The transport layer performs no type checking on this argument. When the service uses the MongoDB adapter, these objects pass through getObjectId() and land directly in the MongoDB query as operators. Sending {$ne: null} as the id mat...
NoSQL injection in Parse Server's password reset and email verification endpoints allows unauthenticated attackers to extract authentication tokens by injecting MongoDB query operators through the unvalidated token parameter. Affected deployments running MongoDB with these features enabled are vulnerable to email verification bypass and password reset token theft. The vulnerability is fixed in versions 8.6.14 and 9.5.2-alpha.1.

This vulnerability affects deployments where database access is granted to untrusted users and requires valid credentials to exploit. No patch is currently available.
MongoDB proxy port connections bypass connection accounting mechanisms, allowing unauthenticated remote attackers to exhaust server resources and trigger denial of service without authentication. Servers relying on connection limits for resource management are vulnerable to crashes when connection counts are artificially inflated through the proxy protocol. No patch is currently available for this high-severity issue affecting MongoDB deployments.
MongoDB replica set replication can be disrupted when oversized documents are inserted, preventing secondaries from synchronizing oplog entries with the primary and potentially causing server crashes. Authenticated users with write access can trigger this denial of service condition to destabilize replica set availability. No patch is currently available for this vulnerability.
MongoDB server's resource locking mechanism can cause unintended collisions between collections due to improper internal encoding, leading to service denial of availability. Authenticated users can trigger this condition to disrupt database operations across affected collections without requiring user interaction. No patch is currently available to remediate this vulnerability.
MongoDB instances are vulnerable to denial of service attacks when processing specially crafted unauthenticated messages that trigger memory exhaustion and server crashes. An unauthenticated remote attacker can exploit this vulnerability to disable MongoDB availability without requiring valid credentials or user interaction. No patch is currently available for this vulnerability.

Packetbeat's MongoDB protocol parser fails to properly validate array indices, enabling attackers to trigger buffer overflows via malformed network packets sent to monitored interfaces. Organizations running Packetbeat with MongoDB protocol parsing enabled could experience denial of service conditions when processing specially crafted traffic. No patch is currently available for this vulnerability.
Flagforge versions 2.3.2 and earlier suffer from a Regular Expression Denial of Service (ReDoS) vulnerability in the user profile API endpoint that accepts unvalidated usernames containing regex metacharacters, allowing unauthenticated remote attackers to trigger excessive CPU consumption and deny service to legitimate users. The MongoDB regex engine processes these malicious patterns inefficiently, making the platform unavailable without administrator intervention. No patch is currently available; users should implement WAF rules to filter regex metacharacters from username inputs as a temporary mitigation.

MongoDB Server's bundled MozJS (SpiderMonkey) scripting engine unconditionally registers a module loading hook that permits JavaScript code - executing inside aggregation pipeline stages - to read arbitrary files from the host filesystem using the mongod process's OS-level privileges. Any authenticated database user with permission to run JavaScript-enabled aggregation stages can craft pipeline commands to exfiltrate sensitive host files such as private keys, configuration files, or application secrets, bypassing MongoDB's own role-based access controls. No public exploit code or CISA KEV listing exists at time of analysis, but low attack complexity and a default-enabled attack surface make this a meaningful threat in any deployment with untrusted or broadly-credentialed users.
Out-of-bounds heap read in MongoDB Server's BSON CodeWScope element accessors lets an authenticated user disclose adjacent heap memory or crash the server (denial of service) by submitting a crafted aggregation pipeline. The exploit path abuses malformed BSONColumn (columnar/compressed BSON) data whose CodeWScope element bypasses the normal wire-level BSON validation, so an unchecked size field is trusted during decompression. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; the CVSS 4.0 base score is 7.1, driven mainly by high availability impact.
Denial of service in MongoDB's aggregation framework allows an authenticated database user with write access to crash the mongod process by triggering a specific data type conversion operation that consumes disproportionate memory, causing the operating system's out-of-memory killer to terminate the process under memory pressure. Affected are MongoDB server deployments where low-privileged users can run aggregation queries; the CVSS 4.0 score is 7.1 with high availability impact and no confidentiality or integrity impact. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Denial of service in MongoDB Server (mongod) allows an authenticated user with aggregation privileges to force the operating system to terminate the mongod process under memory pressure by abusing the $rankFusion and $scoreFusion hybrid-search aggregation stages. The flaw sits in the server's error-handling path and requires only the ability to run aggregation queries, causing an OOM-triggered crash of the database instance. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Excessive CPU consumption in MongoDB Server's awaitable hello command exhaust mode allows unauthenticated remote clients to degrade server availability without any credentials. A specific parameter combination triggers a server-side response loop that bypasses normal throttling mechanisms, meaning even a small number of malicious connections can measurably impair database availability. No active exploitation has been confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis; the CVSS 4.0 score of 6.9 with VA:L reflects a real but bounded availability impact.
MongoDB's mongod daemon can be crashed by any authenticated user holding only read-only privileges, dropping database service for every connected client until an operator restarts the process. The root cause is CWE-617 (Reachable Assertion) inside the aggregation framework's engine selection logic - a state the codebase assumed unreachable that a crafted combination of aggregation options can actually trigger. No public exploit code has been identified at time of analysis and no CISA KEV listing exists, but the PR:L attack vector makes this a reliable insider-threat and post-compromise availability weapon against any network-reachable MongoDB deployment.
Memory corruption in MongoDB standalone mongod servers running with compute mode enabled allows remote attackers to crash the process (denial of service) or trigger undefined behavior by supplying maliciously crafted BSON data that is mishandled during aggregation pipeline processing (CWE-122 heap overflow). Only servers explicitly started in the non-default compute mode are affected. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV; the vendor rates it CVSS 4.0 9.2 (Critical) despite high attack complexity and a required precondition.
Denial of service in MongoDB's mongod server allows any authenticated user holding only read privileges to crash the database by submitting aggregation pipeline expressions that invoke server-side JavaScript, triggering a use-after-free (CWE-416) during document processing. The flaw affects availability only and requires valid low-privilege credentials; no public exploit identified at time of analysis and it is not listed in CISA KEV.
MongoDB Server terminates abnormally during outbound TLS handshake when a remote peer delivers a malformed OCSP response, producing a denial-of-service condition against the database process itself. OCSP stapling validation is enabled by default for all outgoing TLS connections, meaning no operator misconfiguration is required to expose this attack surface - any MongoDB server initiating TLS connections is potentially reachable. No public exploit code exists and no CISA KEV listing is present at time of analysis, but the default-enabled feature combined with the adjacent-network attack vector makes this a credible operational risk for MongoDB clusters traversing partially trusted or shared network segments.
Denial of service in MongoDB Server allows an authenticated user to exhaust CPU or trigger out-of-memory conditions by submitting a crafted Queryable Encryption 'find' payload whose unvalidated field drives an internal computation loop. The resulting resource exhaustion degrades availability for all other operations on the affected instance. No public exploit identified at time of analysis, and it is not listed in CISA KEV; the issue is tracked internally as MongoDB SERVER-127566.
MongoDB's cursor termination authorization logic fails to scope privileges to the correct database namespace, allowing an authenticated low-privilege user to terminate active cursors on databases they do not administer. Exploitation requires the attacker to hold cursor termination rights on at least one database, limiting the practical threat to malicious or compromised internal users. No public exploit has been identified at time of analysis, and this vulnerability has not been added to the CISA Known Exploited Vulnerabilities catalog.
Improper authorization in MongoDB Server allows a local attacker holding a valid trusted-CA X.509 certificate to obtain unintended database roles when PROXY protocol v2 is used over the Unix domain socket, because certificate-derived roles bypass the configured tlsCATrusts allow-list during MONGODB-X509 authentication. An attacker with local access to the proxy socket can therefore escalate to roles they were never granted, compromising confidentiality and integrity of data. Tracked via MongoDB SERVER-128387 and rated CVSS 4.0 7.2 (High); no public exploit identified at time of analysis and it is not listed in CISA KEV.
Information disclosure in MongoDB's server-side JavaScript engine allows authenticated database users to read fragments of internal server process memory. The flaw stems from improper handling of DBPointer objects during BSON serialization, causing uninitialized or adjacent memory contents to be returned to the client. Only deployments that enable server-side JavaScript are affected; no public exploit has been identified at time of analysis and it is not listed in CISA KEV.
Denial of service in MongoDB Server allows an authenticated user holding only read-only privileges to crash the mongod process by submitting an aggregation pipeline that uses the $linearFill window function with a maliciously typed sortBy expression. Because the required privilege level is minimal (any read user) and the trigger is a single crafted query over the normal database wire protocol, a low-privilege account can repeatedly terminate the database node. No public exploit has been identified at time of analysis, and the issue is not listed in CISA KEV; EPSS was not provided.
Denial of service in MongoDB allows an authenticated attacker to exhaust server CPU by submitting query operations that use deeply nested $jsonSchema validation constructs, producing a runaway CPU-bound operation that cannot be halted via standard administrative controls such as killOp. Reported by MongoDB's own CNA (SERVER-125872) and classified as inefficient algorithmic complexity (CWE-407), with no public exploit identified at time of analysis. The inability to interrupt the operation elevates this above a routine resource-consumption bug because normal recovery tooling is ineffective.
Denial of service against the MongoDB mongod process is achievable by any authenticated user holding standard read/write privileges by submitting a crafted aggregation command that exploits insufficient input validation in the bundled libmongocrypt library. An integer overflow (CWE-190) in libmongocrypt allows attacker-controlled payload values to produce an excessively large memory allocation request, causing the operating system to terminate the mongod process under an out-of-memory condition. No public exploit has been identified and this vulnerability is not listed in the CISA KEV catalog at time of analysis.
Integrity corruption in MongoDB's Queryable Encryption on sharded clusters lets an authenticated user with write access to a QE-enabled collection tamper with server-controlled encryption metadata by routing crafted write commands through the mongos router, breaking the correctness of encrypted queries. The CVSS 4.0 vector (VI:H, VC:N, VA:N) confirms this is an integrity-only issue despite the input's 'Information Disclosure' tag, which appears mislabeled. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Incorrect authorization in MongoDB's $listSessions aggregation stage allows any authenticated user to enumerate session metadata cluster-wide - a capability that should be restricted to cluster-level administrators. Exposed data includes active session identifiers, associated usernames, and activity timestamps, which in combination represent a meaningful secondary risk for session-hijacking attempts against high-value accounts. No public exploit code exists and this is not listed in CISA KEV at time of analysis; however, the low exploitation bar (any valid MongoDB account) in multi-tenant environments elevates real-world concern above the moderate CVSS score alone.
Authorization bypass in MongoDB Server allows an authenticated user holding limited read privileges to read documents from collections they are not permitted to access, exploiting a discrepancy between how the $graphLookup aggregation stage is authorized versus how it is executed when the target collection is referenced inside an existing view's pipeline definition. The flaw (CWE-863, Incorrect Authorization) yields cross-collection data disclosure with no integrity or availability impact. No public exploit was identified at time of analysis and the issue is not listed in CISA KEV; it was self-reported by MongoDB's CNA and tracked in SERVER-127357.
Authorization bypass in MongoDB Server allows an authenticated low-privileged user to read and write documents that should be shielded by role-based, query-level access controls. Because the server insufficiently validates certain client-supplied command parameters, crafted find, update, delete, and aggregate commands can sidestep the access boundaries enforced for a user's role. The flaw only manifests in non-apiStrict deployments (the default), and per the vendor CVSS 4.0 vector it yields high confidentiality and integrity impact; no public exploit has been identified at time of analysis.
Denial of service in MongoDB Server (mongod) allows an authenticated user holding only basic write privileges to crash the database process by submitting a crafted transaction command that omits some required fields. The inconsistent validation of related transaction parameters trips a fatal internal invariant (CWE-617), aborting mongod and interrupting availability for all clients. No public exploit has been identified at time of analysis, and the flaw is not listed in CISA KEV; impact is limited to availability, with no data disclosure or integrity effect.
Atlas Search integration in MongoDB's sharded topology exposes a per-user access control bypass to authenticated low-privileged users. The `$search` and `$searchMeta` aggregation pipeline stages rely on internal routing fields that are intended to be injected exclusively by the trusted mongos router during sharded query planning; due to insufficient input validation (CWE-20), an authenticated client can supply these fields directly and circumvent the access controls normally enforced per-user. No public exploit has been identified at time of analysis, and the vulnerability is not listed in CISA KEV; the CVSS 4.0 score of 6.0 reflects the combination of high confidentiality impact against a sharded-only attack surface requiring authenticated access.
Denial of service in MongoDB Server allows an authenticated database user to submit an aggregation/query expression that generates very large arrays, forcing the server to allocate oversized intermediate objects in memory and crash with an out-of-memory (OOM) error. Reported by MongoDB's own CNA and tracked in SERVER-124355, the flaw carries a CVSS 4.0 base score of 7.1 with an availability-only impact (VA:H). No public exploit identified at time of analysis, and it is not listed in CISA KEV.
Denial of service in MongoDB Server (mongod) lets any authenticated user with aggregation-pipeline privileges crash the database process by invoking the internal `$_internalIndexKey` aggregation expression against a compound wildcard index. The expression fails to handle compound wildcard index specifications, tripping an internal consistency check (assertion) that aborts the server. No public exploit identified at time of analysis, and the flaw is reported by MongoDB's own CNA as a Denial of Service issue with no confidentiality or integrity impact.
Memory disclosure and denial of service in MongoDB Server's server-side JavaScript engine allow an authenticated user with read privileges and JavaScript execution rights to read freed heap memory or crash the mongod process. The flaw is triggered during BSON-to-JavaScript array conversion when operators such as $where or $function are evaluated. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV; it was self-reported by MongoDB.
Information disclosure in MongoDB Server allows authenticated users holding the read role to obtain small amounts of uninitialized stack memory by submitting specially-crafted filemd5 commands. The flaw stems from CWE-457 (Use of Uninitialized Variable) in the filemd5 command handler, and while no public exploit has been identified at time of analysis, the low attack complexity and network reachability make it a credible insider/credential-theft risk against MongoDB databases.
Feathersjs is a framework for creating web APIs and real-time applications with TypeScript or JavaScript. From 5.0.0 to before 5.0.42, Socket.IO clients can send arbitrary JavaScript objects as the id argument to any service method (get, patch, update, remove). The transport layer performs no type checking on this argument. When the service uses the MongoDB adapter, these objects pass through getObjectId() and land directly in the MongoDB query as operators. Sending {$ne: null} as the id mat...

Packetbeat's MongoDB protocol parser fails to properly validate array indices, enabling attackers to trigger buffer overflows via malformed network packets sent to monitored interfaces. Organizations running Packetbeat with MongoDB protocol parsing enabled could experience denial of service conditions when processing specially crafted traffic. No patch is currently available for this vulnerability.
Flagforge versions 2.3.2 and earlier suffer from a Regular Expression Denial of Service (ReDoS) vulnerability in the user profile API endpoint that accepts unvalidated usernames containing regex metacharacters, allowing unauthenticated remote attackers to trigger excessive CPU consumption and deny service to legitimate users. The MongoDB regex engine processes these malicious patterns inefficiently, making the platform unavailable without administrator intervention. No patch is currently available; users should implement WAF rules to filter regex metacharacters from username inputs as a temporary mitigation.
