CVE-2026-24762 (GCVE-0-2026-24762)

Vulnerability from cvelistv5 – Published: 2026-02-03 16:06 – Updated: 2026-02-03 17:11

Title

RustFS Logs Sensitive Credentials in Plaintext

Summary

RustFS is a distributed object storage system built in Rust. From versions alpha.13 to alpha.81, RustFS logs sensitive credential material (access key, secret key, session token) to application logs at INFO level. This results in credentials being recorded in plaintext in log output, which may be accessible to internal or external log consumers and could lead to compromise of sensitive credentials. This issue has been patched in version alpha.82.

Severity ?

6.9 (Medium)

GHSA-R54G-49RX-98CR

Vulnerability from github – Published: 2026-02-03 17:37 – Updated: 2026-02-03 19:44

Summary

RustFS Logs Sensitive Credentials in Plaintext

Details

Summary

RustFS logs sensitive credential material (access key, secret key, session token) to application logs at INFO level. This results in credentials being recorded in plaintext in log output, which may be accessible to internal or external log consumers and could lead to compromise of sensitive credentials. This vulnerability is classified as an information disclosure issue (CWE-532).

Details

The server writes newly generated STS credential information including the access key, secret key, and session token to logs. The following excerpts from application logs demonstrate this:

[2026-01-17 09:13:23.127767 +11:00] INFO [rustfs::admin::handlers::sts] [rustfs/src/admin/handlers/sts.rs:138] [rustfs-worker:ThreadId(4)] AssumeRole get new_cred Credentials { access_key: "5UGH6TM44IPA81AH1WZE", secret_key: "3BQ-KnO_iB5ovmd5SU4wIK6sFfaPTliftvQ_iNLS", session_token: "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJleHAiOjE3Njg2NDQ4MDMsInBhcmVudCI6InJ1c3Rmc2FkbWluIn0.F9ZhARXyU0cB6QoFMElKK5tns_RFQM9WlpMiGVuuDOpOfNrbEKE_9IK1oaJ_yqDsBlK115uYOcQcGohjgUPhOQ", expiration: Some(2026-01-17 10:13:23.0 +00:00:00), status: "on", parent_user: "rustfsadmin", groups: None, claims: None, name: None, description: None }

By inspecting logs, an attacker or unauthorized internal user with access to logs could retrieve these credentials and use them to authenticate to RustFS services or perform other unauthorized actions.

Impact

Information Exposure: Plaintext authentication credentials appear in log files that may be retained, backed up, or forwarded to centralized logging systems.
Credential Compromise: Access keys, secret keys, and session tokens may be used by unauthorized individuals to authenticate to RustFS services or hijack sessions.
Insider Threat: Even users with limited access who can read logs may gain elevated access if they retrieve credential material.
Compliance Risk: Logging sensitive authentication material may violate organizational policies and industry compliance standards (e.g., PCI-DSS, SOC2, ISO 27001) that forbid exposure of authentication secrets in logs

Remediation

Do not include secrets in log output — redact secret_key, session_token, and similar fields.
Log only safe identifiers such as non-sensitive IDs (e.g., parent_user, trace ID).

Severity ?

6.9 (Medium)

This results in credentials being recorded in plaintext in log output, which may be accessible to internal or external log consumers and could lead to compromise of sensitive credentials. This vulnerability is classified as an information disclosure issue (CWE-532).\n\n### Details\nThe server writes newly generated STS credential information including the access key, secret key, and session token to logs. The following excerpts from application logs demonstrate this:\n\n```\n[2026-01-17 09:13:23.127767 +11:00] INFO [rustfs::admin::handlers::sts] [rustfs/src/admin/handlers/sts.rs:138] [rustfs-worker:ThreadId(4)] AssumeRole get new_cred Credentials { access_key: \"5UGH6TM44IPA81AH1WZE\", secret_key: \"3BQ-KnO_iB5ovmd5SU4wIK6sFfaPTliftvQ_iNLS\", session_token: \"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJleHAiOjE3Njg2NDQ4MDMsInBhcmVudCI6InJ1c3Rmc2FkbWluIn0.F9ZhARXyU0cB6QoFMElKK5tns_RFQM9WlpMiGVuuDOpOfNrbEKE_9IK1oaJ_yqDsBlK115uYOcQcGohjgUPhOQ\", expiration: Some(2026-01-17 10:13:23.0 +00:00:00), status: \"on\", parent_user: \"rustfsadmin\", groups: None, claims: None, name: None, description: None }\n```\nBy inspecting logs, an attacker or unauthorized internal user with access to logs could retrieve these credentials and use them to authenticate to RustFS services or perform other unauthorized actions.\n\n### Impact\n- Information Exposure: Plaintext authentication credentials appear in log files that may be retained, backed up, or forwarded to centralized logging systems.\n- Credential Compromise: Access keys, secret keys, and session tokens may be used by unauthorized individuals to authenticate to RustFS services or hijack sessions.\n- Insider Threat: Even users with limited access who can read logs may gain elevated access if they retrieve credential material.\n- Compliance Risk: Logging sensitive authentication material may violate organizational policies and industry compliance standards (e.g., PCI-DSS, SOC2, ISO 27001) that forbid exposure of authentication secrets in logs\n\n### Remediation\n- Do not include secrets in log output \u2014 redact secret_key, session_token, and similar fields.\n- Log only safe identifiers such as non-sensitive IDs (e.g., parent_user, trace ID).",
