CVE-2026-48708: Concurrent Template Parsing Race Condition in OliveTin leading to Cross-Request Command Contamination

Vulnerability ID: CVE-2026-48708
CVSS Score: 7.5
Published: 2026-06-24

CVE-2026-48708 details a critical concurrency synchronization flaw in OliveTin versions < 3000.13.0. A shared package-level text/template.Template instance is accessed concurrently across multiple goroutines without proper synchronization. When concurrent request processing occurs, a race condition causes Go runtime panics or command contamination across separate sessions, enabling denial of service or execution of contaminated commands.

TL;DR

A concurrent template parsing race condition in OliveTin allows authenticated users to crash the daemon or cause cross-request command contamination, potentially executing unauthorized commands.

Technical Details

  • CWE ID: CWE-362
  • Attack Vector: Network (AV:N)
  • CVSS v3.1 Score: 7.5 (High)
  • EPSS Score: 0.00349 (0.349%)
  • Exploit Status: None / Theoretical
  • CISA KEV Status: Not Listed
  • Primary Impact: Denial of Service / Command Contamination

Affected Systems

  • OliveTin versions prior to 3000.13.0
  • OliveTin: < 3000.13.0 (Fixed in: 3000.13.0)

Code Analysis

Commit: d74da93

Clone templates before parsing to prevent race conditions during concurrent access.

Mitigation Strategies

  • Upgrade OliveTin to version 3000.13.0 or later.
  • Implement strict rate-limiting on reverse proxies to limit concurrent execution requests to 1.
  • Restrict access to the OliveTin control panel using strong multi-factor authentication and trusted IP networks.

Remediation Steps:

  1. Identify current OliveTin deployments running versions prior to 3000.13.0.
  2. Pull the updated Docker image or download the latest binary from the official release page: https://github.com/OliveTin/OliveTin/releases/tag/3000.13.0
  3. Deploy the update and restart the daemon to apply the template isolation patches.
  4. Validate the update by checking logs for the absence of Go concurrent map write panic traces.
