Because these errors are produced before authentication, authorization, or any resolver runs, an unauthenticated client possessing only the public application ID can trigger errors on Pointer or Relation fields to r… CWE-209Jul 24, 2026 | CVSS6.3v4.0 | EPSS0.32% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-64627MEDIUM | Parse Server 9.0.0 Schema Disclosure via GraphQL Variable CoercionParse Server versions >= 9.0.0 before 9.10.0-alpha.4 and versions before 8.6.85 contain a schema disclosure vulnerability. When the GraphQL API is mounted with public introspection disabled (graphQLPublicIntrospection: false, the default), schema-derived 'Did you mean ...?' suggestions were still returned in GraphQL error messages produced during variable coercion, which were not covered by the introspection-hardening control (that only handled validation errors). An unauthenticated caller posse… CWE-209Jul 21, 2026 | CVSS6.9v4.0 | EPSS0.279% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
Parse Server 9.0.0 Stored XSS via malformed Content-TypeParse Server is affected by a stored cross-site scripting (XSS) vulnerability in versions >= 9.0.0, < 9.10.0-alpha.2 and <= 8.6.83. When an uploaded file's extension is not recognized by the mime package, Parse Server preserves the client-supplied Content-Type. A malformed Content-Type that is not a valid type/subtype media type (e.g., 'image', 'image/', or 'image//svg+xml') bypasses the fileUpload.fileExtensions blocklist and is stored unchanged. On storage adapters that persist and serve the u… CWE-434Jul 11, 2026 | CVSS2.1v4.0 | EPSS0.245% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX | |
Parse Server: LiveQuery discloses object data to a subscriber across an ACL read-access changeParse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.9.1-alpha.13 and 8.6.83, a LiveQuery subscriber could receive object field values they were not authorized to read when a single save changed both an object field and the subscriber's ACL read access, because leave and enter events included the wrong object state. This issue is fixed in versions 9.9.1-alpha.13 and 8.6.83. CWE-200Jul 8, 2026 | CVSS2.3v4.0 | EPSS0.386% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX | |
CVE-2026-57480HIGH | Parse Server: Denial of service via exponential-time processing of deeply nested query operatorsParse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.9.1-alpha.12 and 8.6.82, deeply nested $or, $and, and $nor query condition operators in the REST API or LiveQuery query handling could trigger exponential-time processing in the internal query-traversal helper and block the Node.js event loop. This issue is fixed in versions 9.9.1-alpha.12 and 8.6.82. CWE-407Jul 8, 2026 | CVSS8.7v4.0 | EPSS0.335% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
Parse Server: Stored XSS via non-standard file extension bypassing file upload extension blocklistParse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.9.1-alpha.11 and 8.6.81, the default fileUpload.fileExtensions blocklist could be bypassed by uploading a file with a non-standard or compound extension and dangerous content type, allowing storage adapters such as S3 and GCS to serve attacker-supplied active content and enable stored cross-site scripting. This issue is fixed in versions 9.9.1-alpha.11 and 8.6.81. CWE-434Jul 8, 2026 | CVSS2.1v4.0 | EPSS0.406% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX | |
CVE-2021-47987HIGH | Parse Server - Arbitrary Code Execution via Malicious Version TagsParse Server before 4.10.0 was affected by a supply chain incident in which incorrect version tags were pushed to the official repository pointing to an unreviewed personal fork of a contributor with write access. No releases were published with these tags; a project was exposed only if it defined a git-based dependency referencing one of the affected tags (for example, parse-server#4.9.3). The code behind the tags was not reviewed or approved, and although no malicious code was identified, the … CWE-494Jun 25, 2026 | CVSS7.7v4.0 | EPSS0.12% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2021-47986HIGH | Parse Server - Unreviewed Code Execution via Malicious Version TagsParse Server before 4.10.0 contains a supply chain vulnerability where incorrect version tags were pushed to the repository linking to unreviewed code in a personal fork.

CVE-2026-53726MEDIUM | Parse Server: Relation `$relatedTo` query bypasses `protectedFields` and owning-object ACLParse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.80 and 9.9.1-alpha.6, a relation query using the $relatedTo operator could read the membership of a Relation field even when that field was hidden from the requesting client by protectedFields, and even when the object owning the relation was not readable by the client under its ACL or class-level permissions. The request requires only the public API credentials that Pars… CWE-639Jun 12, 2026 | CVSS6.9v4.0 | EPSS0.276% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-53725MEDIUM | Parse Server: Endpoints `/login` and `/verifyPassword` disclose MFA secrets and protected fields when `_User` get is deniedParse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. From version 9.8.0 to before version 9.9.1-alpha.5, apps that enable MFA and deny get on the _User class via Class-Level Permissions could expose sensitive user data through the /login and /verifyPassword endpoints. These endpoints re-fetch the user through the access-controlled query pipeline (CLP, protectedFields, auth-adapter sanitizers) before responding. When that re-fetch was denied by t… CWE-200Jun 12, 2026 | CVSS5.9v4.0 | EPSS0.252% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
Parse Server: Stored XSS via trailing-dot filename bypassing file upload extension blocklistParse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.79 and 9.9.1-alpha.4, the default file upload extension blocklist can be bypassed by appending a trailing dot to a filename whose extension would otherwise be blocked (e.g. poc.svg.). The trailing dot causes the extension parser to extract an empty string, which short-circuits the blocklist check, and the attacker-controlled Content-Type is forwarded to the storage adapte… | CVSS2.1v4.0 | EPSS0.281% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX | |
CVE-2026-50008MEDIUM | Parse Server: Server option routeAllowList is bypassable through batch sub-requestsParse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. From version 9.8.0 to before version 9.9.1-alpha.3, the routeAllowList server option restricts external client access to a configured list of REST API routes. The check is only enforced as Express middleware against the outer HTTP request URL, so the /batch handler dispatches each sub-request to the internal router without re-running the allow-list check. An external caller whose outer route m… CWE-863Jun 12, 2026 | CVSS6.9v4.0 | EPSS0.343% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-47138HIGH | Parse Server: Pre-authentication denial of service via client version header regex backtrackingParse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.77 and 9.9.1-alpha.1, an unauthenticated attacker who knows a publicly-known Parse Application ID can submit a single HTTP request whose client SDK version field contains adversarial input that triggers polynomial backtracking in a request-header parser. The parsing runs before session authentication and before rate limiting on every /parse/* request, so the request consu… CWE-1333Jun 12, 2026 | CVSS8.7v4.0 | EPSS0.584% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |

Prior to versions 8.6.78 and 9.9.1-alpha.2, Parse Server's GraphQL endpoint discloses schema metadata to unauthenticated callers through Did you mean ...? suggestions embedded in GraphQL validation-error messages. An unauthenticated caller who knows only the public application id can iteratively send malformed queries to reconstruct class names, field names, argument names, mutation names, and… CWE-209Jun 12, 2026 | CVSS6.9v4.0 | EPSS0.291% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
Parse Server: MFA SMS one-time password accepted twice under concurrent loginParse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 8.6.76 and 9.9.0-alpha.2, a race condition in the MFA SMS one-time password (OTP) login path allows two concurrent /login requests carrying the same OTP to both succeed and both receive valid session tokens, breaking the single-use property of the OTP. The vulnerability requires the attacker to already possess the victim's password and intercept the active SMS OTP (e.g. via SIM swap, … CWE-362May 12, 2026 | CVSS2.1v4.0 | EPSS0.236% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX | |

Prior to 9.8.0-alpha.7 and 8.6.75, the GET /sessions/me endpoint returns _Session fields that the server operator explicitly configured as protected via the protectedFields server option. Any authenticated user can retrieve their own session's protected fields with a single request. The equivalent GET /sessions and GET /sessions/:objectId endpoints correctly strip protected fields. This vulner… CWE-863Apr 7, 2026 | CVSS5.3v4.0 | EPSS0.193% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-39321MEDIUM | Parse Server has a login timing side-channel reveals user existenceParse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.8.0-alpha.6 and 8.6.74, he login endpoint response time differs measurably depending on whether the submitted username or email exists in the database. When a user is not found, the server responds immediately. When a user exists but the password is wrong, a bcrypt comparison runs first, adding significant latency. This timing difference allows an unauthenticated attacker to enumera… CWE-208Apr 7, 2026 | CVSS6.3v4.0 | EPSS0.23% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
Parse Server has a file upload Content-Type override via extension mismatchParse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 8.6.73 and 9.7.1-alpha.4, a file can be uploaded with a filename extension that passes the file extension allowlist (e.g., .txt) but with a Content-Type header that differs from the extension (e.g., text/html). The Content-Type is passed to the storage adapter without consistency validation. Storage adapters that store and serve the provided Content-Type (such as S3 or GCS) serve the … CWE-436Apr 6, 2026 | CVSS2.1v4.0 | EPSS0.162% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX | |
