Vulnerability from cvelistv5 – Published: 2026-07-08 13:48 – Updated: 2026-07-08 14:23

Title

Capgo - Arbitrary R2 Object Deletion via Mutable r2_path in app_versions

Summary

Capgo before 12.128.2 allows upload-scoped API keys to modify the mutable app_versions.r2_path field through PostgREST, enabling retargeting to arbitrary R2 bundle objects. Attackers can patch r2_path to point to victim objects, soft-delete the attacker-controlled version, and trigger the on_version_update cleanup function to delete the victim R2 object, causing denial of service and bundle availability disruption.

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.
