About CVE-2026-57941

What is CVE-2026-57941 and which systems are affected?

CVE-2026-57941 is a use-after-free vulnerability (CWE-416) in the Apache HTTP Server's mod_http2 module. It affects Apache HTTP Server versions 2.4.0 through 2.4.68 (inclusive) when mod_http2 is enabled. The vulnerability allows remote, unauthenticated attackers to exploit memory corruption, potentially leading to denial of service or remote code execution. Note: Only servers with mod_http2 enabled and processing HTTP/2 connections are affected. [Official advisory]

How severe is CVE-2026-57941?

CVE-2026-57941 has a CVSS v3.1 base score of 9.8 (Critical). The vulnerability is network-exploitable, requires no authentication or user interaction, and can result in high impact to confidentiality, integrity, and availability. Note: The critical rating means immediate mitigation is recommended. [CVE Project record]

What are the recommended mitigation steps for CVE-2026-57941?

To mitigate CVE-2026-57941, upgrade Apache HTTP Server to version 2.4.69 or later, which contains the official fix (upstream revision r1938665). If immediate patching is not possible, disable the mod_http2 module or HTTP/2 protocol negotiation on affected servers until the upgrade can be performed. Note: Disabling HTTP/2 may impact performance or compatibility for some applications. [Official advisory]

IONIX Platform Capabilities for Zero-Day and CVE Response

How does IONIX detect and validate exposure to CVE-2026-57941?

IONIX continuously maps your entire external attack surface using multi-factor discovery methods such as DNS analysis, certificate mapping, and metadata inspection. For CVE-2026-57941, IONIX identifies all assets running vulnerable Apache HTTP Server versions with mod_http2 enabled, monitors threat intelligence feeds for exploit activity, and applies AI to evaluate exploitability. The platform validates exposures by running safe, targeted exploit simulations in production environments, confirming which assets are truly at risk. Note: Validation is limited to externally reachable assets; internal-only systems require additional controls. [IONIX Threat Center]

What is Live Exposure Defense and how does it accelerate zero-day response?

Live Exposure Defense is an IONIX capability that commits to a 12-hour SLA from CVE publication to identifying every potentially affected external asset. Exploitability validation runs automatically within the same window, enabling rapid prioritization and mitigation. This agentic automation ensures that security teams can act on confirmed, actionable exposures before attackers exploit them. Note: The 12-hour SLA applies to external, internet-facing assets; internal assets require separate processes. [IONIX Threat Center]

How does IONIX prioritize and drive remediation for critical CVEs like CVE-2026-57941?

IONIX filters vulnerabilities by attacker-centric criteria: internet reachability, authentication requirements, and evidence of exploitation in the wild. The platform bundles validated exposures into remediation clusters, routes them through integrations with ticketing (Jira, ServiceNow), SOAR, and SIEM tools, and prioritizes based on asset criticality, exploitability, and blast radius. This workflow shortens mean time to remediation (MTTR) and reduces analyst fatigue. Note: Prioritization is based on external exposure; internal risk context may require additional review. [Why IONIX]

What integrations does IONIX support for zero-day and CVE remediation workflows?

IONIX integrates with ticketing systems (Jira, ServiceNow), SIEM platforms (Splunk, Microsoft Sentinel, and any SIEM via API), cloud platforms (AWS Control Tower, AWS PrivateLink), CDN/WAF providers (Cloudflare WAF), collaboration tools (Slack via RSS), and security tools (Wiz, Prisma Cloud). These integrations enable automated, actionable remediation and real-time alerting for critical exposures. Note: Some integrations may require additional configuration or licensing. [Integration details]

New CVE Detected

CVE-2026-57941 – Use-After-Free / Potential RCE – Apache HTTP Server 2.4.0–2.4.68

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

Summary

CVE-2026-57941 is a use-after-free vulnerability (CWE-416) in Apache HTTP Server’s mod_http2 module, caused by re-entrancy issues around a shared session->bbtmp buffer. It affects Apache HTTP Server versions 2.4.0 through 2.4.68 and carries a CVSS v3.1 base score of 9.8 (Critical), reflecting a network-exploitable, low-complexity attack path with no authentication or user interaction required.

Technical details

  • Root cause: Re-entrant handling of a shared temporary bucket brigade (session->bbtmp) within mod_http2 leads to memory being freed and subsequently reused/accessed (use-after-free).
  • Trigger conditions: Exploitation requires the mod_http2 module to be enabled and HTTP/2 connections processed by the affected server.
  • Attack vector: Remote, network-based; no privileges or user interaction required (AV:N/AC:L/PR:N/UI:N).
  • Impact: The CVSS vector indicates high impact to confidentiality, integrity, and availability, consistent with memory-corruption issues that can lead to crashes (denial of service) or, depending on exploitability, more severe outcomes such as remote code execution.

Affected software

  • Apache HTTP Server versions 2.4.0 through 2.4.68 (inclusive), when mod_http2 is enabled.

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 Apache HTTP Server to version 2.4.69 or later, which contains the fix for this issue (committed upstream as revision r1938665).
  • If no patch can be applied immediately: Disable the mod_http2 module (or disable HTTP/2 protocol negotiation) on affected servers until the upgrade can be performed, since the flaw is specific to HTTP/2 request handling.

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.
