New CVE Detected

CVE-2026-73240 – Git Argument Injection (Remote Code Execution Risk) – Apache Allura before 1.19.1

Be the first to know when new zero-days emerge:

Summary

CVE-2026-73240 is a critical git argument injection vulnerability in Apache Allura, an open-source platform for hosting software development projects (source code, tickets, wikis, forums, etc.). Specifically crafted user input can be injected as arguments into git commands executed by Allura, and the flaw carries a CVSS v3.1 base score of 9.8 (Critical). All Allura deployments running versions prior to 1.19.1 are affected and should be upgraded immediately.

Technical details

  • Root cause: Improper Neutralization of Argument Delimiters in a Command (CWE-88) — Allura fails to adequately sanitize certain user-supplied input before passing it to underlying git command invocations, allowing attacker-controlled strings to be interpreted as command-line arguments/options rather than plain data.
  • Trigger conditions: An attacker submits specifically crafted input (e.g., via repository-related operations handled by Allura) that is subsequently used to construct a git command line.
  • Attack vector: Network-based (AV:N); the CVSS vector indicates low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N) — meaning an unauthenticated, remote attacker can potentially exploit the issue.
  • Impact: High impact to confidentiality, integrity, and availability (C:H/I:H/A:H). Successful argument injection against git commands can lead to unauthorized data disclosure, manipulation of repository content, or disruption of the affected service, depending on which git operation is abused.
  • This flaw was addressed alongside several other vulnerabilities in the same Apache Allura release (including CVE-2026-69223, CVE-2026-73237, CVE-2026-73238, and CVE-2026-73239), reflecting broader security hardening work in that version.

Affected software

  • Apache Allura: all versions prior to 1.19.1

Severity

  • CVSS v3.1 Base Score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Upgrade all Apache Allura deployments to version 1.19.1 or later, which contains the fix for this vulnerability.
  • If immediate patching is not possible: Restrict network exposure of the Allura instance (e.g., place it behind authentication/VPN or limit access to trusted networks) to reduce the risk of unauthenticated remote exploitation until the upgrade can be applied. Review the Apache Allura 1.19.1 release notes, as the upgrade also requires configuration and database migration steps (e.g., running migration scripts and reindexing), so plan and test the upgrade in a staging environment before applying it in production.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
