CVE-2018-1086 — pcs before versions 0.9.164 and 0.10 is vulnerable to a debug parameter removal bypass

High CVSS 7.5

pcs before versions 0.9.164 and 0.10 is vulnerable to a debug parameter removal bypass. REST interface of the pcsd service did not properly remove the pcs debug argument from the /run_pcs query, possibly disclosing sensitive information. A remote attacker with a valid token could use this flaw to elevate their privilege.

Matched remediation archetype

Information disclosure and sensitive data exposure

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace sensitive data through responses, errors, logs, metrics, traces, caches, exports, files, backups, and client bundles.
  • Identify affected subjects, tenants, retention windows, access controls, and downstream copies without opening unnecessary sensitive records.
  • Review metadata, timing, status, length, and existence signals as well as direct content disclosure.

Remediate safely

  • Minimize collection and output, apply field-level authorization and redaction at a centralized boundary, and return generic external errors.
  • Remove secrets and sensitive data from logs, artifacts, URLs, caches, and client-side bundles; rotate credentials that may have been exposed.
  • Update the affected component and add synthetic-data tests for response, error, observability, and export paths.
