Summary
CVE-2025-57798 is a medium-severity Allocation of Resources Without Limits or Throttling (CWE-770) vulnerability. Its CVSS base score is 5.5 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique SMS Pumping (T1496.003); ranked at the 5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-10 (Concurrent Session Control) and SC-6 (Resource Availability) — see the control section below for these in your framework.

Vulnerability Data
Joplin is an open source note-taking and to-do application that organises notes and lists into notebooks. Versions 3.6.14 and prior contain a Denial of Service (DoS) vulnerability in the title input functionality due to a lack of proper length validation.…
more
This flaw allows an attacker to cause an Out Of Memory (OOM) error and subsequent program termination by inserting an excessively long string into a note's title. This can be triggered either through direct user interface (UI) input or programmatically via the local web service API after compromising an authentication token. There are 2 primary methods of exploitation: via User Interface (UI) Input, and the Local Web Service API. A local user can directly type or paste an extremely long string into the title field when creating or editing a note Joplin runs a local web service (typically on port 41184) that allows programmatic interaction, such as creating or editing notes via HTTP API calls. If an attacker manages to exfiltrate or compromise the user's authentication token (e.g., through malware on the local system, or other local vulnerabilities), they can then send a crafted HTTP POST request to this local API. By including an excessively long string in the title parameter of this request, the application will attempt to allocate an unbounded amount of memory. This issue has been patched in version 3.7.1.

Mitigating Controls (NIST 800-53 r5)
Our mappings, made for this CVE.
Directly enforces a hard limit on concurrent sessions, structurally preventing unbounded resource allocation.
Requires explicit allocation of resources by priority or quota, directly stopping unlimited allocation.
Imposes a limit on consecutive invalid attempts, preventing one specific class of unbounded resource consumption.
Reduces impact of resulting DoS events without preventing the underlying lack of allocation limits.
Mitigating Controls (NIST CSF 2.0)
Our mappings, derived directly from the weakness types (CWEs) cited in the NVD entry via our CWE→CSF cross-walk — links open the control.
Monitoring capacity and taking action to maintain availability directly reduces unchecked resource allocation.
Mitigating Controls (ISO/IEC 27001:2022 Annex A)
Our mappings, derived directly from the weakness types (CWEs) cited in the NVD entry via our CWE→ISO cross-walk — links open the control.
Baseline comparison of CPU, memory and bandwidth usage helps surface uncontrolled resource allocations before they cause service degradation.
A.8.29's combined programme of code review, static analysis, dynamic testing and penetration testing reaches CWE-770 through both SOURCE and RUNTIME: missing throttling, unbounded allocation loops and absent connection limits are patterns static analysis and code review surface, and DoS-style stress testing catches them at runtime. The remainder is bounded and nameable — limits that exist but are set too high for the deployment context, race conditions in resource accounting, and design-level decisions about whether a limit belongs at all — which keeps this below the `full` rung A.8.29 reaches on CWE-89.
A.8.28 mandates secure coding practices — threat modelling, coding standards, peer review, knowledge of common defects — that can catch missing resource limits before code ships, but it is a fallible human practice whose coverage depends on implementer rigour, leaving a nameable remainder that A.8.29 testing reaches more reliably.
Hardening callouts derived
Configuration rules from DISA STIG baselines that bear on weaknesses of the type cited by this CVE. Each rule is shown with the relationship its mapping actually records, against the CWE it was authored against. Derived via CVE→CWE over our cross-walk; rows rated `none` are excluded, and each rule says how its mapping was checked.
Definition changed on 29 October 2026. Until then this section listed every rule rated above none, partial included. From that date it lists rules whose mapping is rated full or mostly and checked at llm_unverified or higher; partial mappings show when you ask.
