CVE-2026-112157 (GCVE-0-2026-112157)

Vulnerability from cvelistv5 – Published: 2026-10-19 15:45 – Updated: 2026-10-22 03:01

Title

MemTensor memmy-agent Memory Service http.ts requireAdminWrite resource consumption

Summary

A weakness has been identified in MemTensor memmy-agent up to 1.0.9/1.1.1/1.2.2. The impacted element is the function requireAdminWrite of the file Memory/src/server/http.ts of the component Memory Service. This manipulation causes resource consumption. Remote exploitation of the attack is possible. The attack is considered to have high complexity. The exploitability is regarded as difficult. The exploit has been made available to the public and could be used for attacks. The exploit is partially overstated. While "POST /api/v1/admin/shutdown" accepts unauthenticated requests when no token is configured, it’s designed for local use and later received cross-origin fixes. Unauthenticated endpoint exposure is confirmed; browser-triggered DoS remains likely but depends on specific browser behavior.

  "details": "A weakness has been identified in MemTensor memmy-agent up to 1.0.9/1.1.1/1.2.2. The impacted element is the function requireAdminWrite of the file Memory/src/server/http.ts of the component Memory Service. This manipulation causes resource consumption. Remote exploitation of the attack is possible. The attack is considered to have high complexity. The exploitability is regarded as difficult. The exploit has been made available to the public and could be used for attacks. The exploit is partially overstated. While \"POST /api/v1/admin/shutdown\" accepts unauthenticated requests when no token is configured, it\u2019s designed for local use and later received cross-origin fixes. Unauthenticated endpoint exposure is confirmed; browser-triggered DoS remains likely but depends on specific browser behavior.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
