Exploitation Conditions

Exploitation requires three concurrent conditions: (1) curl or libcurl must be performing HTTP requests using HTTP Negotiate authentication (SPNEGO/Kerberos/NTLM), which is a non-default configuration that must be explicitly enabled or targeted at a Negotiate-requiring server; (2) curl's connection pooling and reuse must be active (this IS the default behavior, but condition 1 constrains scope significantly); and (3) a previously Negotiate-authenticated connection must be present in the pool and eligible for reuse at the moment a subsequent, differently-scoped request is issued - requiring either multi-user concurrency or sequential request timing to misalign. Limiting factors include the AC:H complexity rating, the non-default nature of HTTP Negotiate in most deployments, and the SSVC 'non-automatable' determination, which means mass exploitation tooling is not feasible. PR:N from the CVSS vector confirms no special privilege level is required from the attacker's perspective, but the attacker must be in a position to influence or observe the request-to-connection mapping - for example, as a co-tenant in a shared application server or as the operator of a target server receiving the misrouted requests.
Impact

The CVSS 3.1 base score of 6.5 (AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:N) presents an initially alarming integrity signal (I:H) but is substantially tempered by the high attack complexity (AC:H), which confirms that exploitation requires specific conditions to align - notably, an active connection pool entry from a previous HTTP Negotiate exchange must be available for misuse. The EPSS score of 0.04% (13th percentile) is extremely low, reflecting the community's current assessment that reliable exploitation at scale is unlikely. SSVC further corroborates this: exploitation status is confirmed as 'none,' the attack is assessed as non-automatable, and technical impact is only partial. There is no CISA KEV listing and no POC identified. Real-world risk is meaningfully below what the raw CVSS score implies: this is not a default-configuration, spray-and-pray attack surface, but a protocol-and-context-specific flaw that requires an attacker to influence or observe curl's connection pool state. Organizations running curl in multi-tenant or multi-user environments where HTTP Negotiate is used - such as intranet proxies, enterprise web services, or CI/CD pipelines hitting Kerberos-protected endpoints - carry the highest realistic exposure.
Exploit ScenarioDerived

In an enterprise environment where curl (or an application embedding libcurl) is used to access Kerberos-protected internal web services, an attacker or a co-located process that can time or trigger HTTP requests could cause curl to reuse an existing HTTP Negotiate-authenticated connection - authenticated as User A - for a request intended to authenticate as User B. The result is that the second request is serviced under User A's security context, potentially allowing access to resources or data scoped to that identity. Attack complexity is high (AC:H), meaning specific timing and connection pool state alignment is required; no public exploit code exists to simplify this.

AnalysisAIv1 – Jun 08, 2026

Wrong reuse of HTTP Negotiate-authenticated connections in curl exposes a high-integrity-impact vulnerability where subsequent HTTP requests may inherit an authentication context they should not, potentially allowing requests to be dispatched under incorrect Negotiate (Kerberos/NTLM/SPNEGO) credentials. Affecting an extraordinarily broad version range - curl 7.10.6 through at least 8.19.0 per EUVD data - this flaw was coordinated and disclosed by curl maintainer Daniel Stenberg via oss-security on 2026-04-29 alongside three related connection-reuse CVEs. No public exploit code has been identified and no active exploitation has been confirmed; a vendor-released patch is available, with downstream fixes confirmed by Red Hat (RHSA-2026:12916) and SUSE.

RemediationAI

The primary remediation is to upgrade curl to the patched version released by the curl project; the exact fixed version should be confirmed at https://curl.se/docs/CVE-2026-5545.html, as no specific fixed version number is independently confirmed in the available intelligence data. Red Hat Enterprise Linux users should apply RHSA-2026:12916 via standard package management; SUSE users should apply the relevant SUSE-SU advisory for their distribution version. If an immediate upgrade is not feasible in environments using HTTP Negotiate authentication, a compensating control is to disable connection reuse explicitly in curl (via CURLOPT_FORBID_REUSE set to 1L in libcurl, or --no-keepalive in the curl CLI) - note this carries a performance cost as each request will require a full connection establishment. Alternatively, avoid HTTP Negotiate authentication entirely where Kerberos or NTLM is not strictly required, substituting token-based or certificate-based auth that is not session-bound to the connection. Monitoring curl usage in environments with enterprise authentication (Active Directory, MIT Kerberos) for anomalous cross-user request patterns is advisable until patching is complete.

Technical ContextAI · show details

curl (CPE: cpe:2.3:a:haxx:curl:*:*:*:*:*:*:*:*) implements connection pooling and reuse as a core performance optimization: rather than tearing down and re-establishing TCP/TLS connections for each request, connections are cached and reused across transfers. HTTP Negotiate authentication (RFC 4559) is a SPNEGO-based scheme that wraps Kerberos or NTLM, negotiating a session-level security context over the connection itself rather than per-request. CWE-613 (Insufficient Session Expiration) is the root cause class: when curl pools a connection that carried a Negotiate authentication handshake, it fails to properly enforce that the negotiated security context is no longer valid or applicable when the connection is later reused for a different request - effectively treating a session-bound credential exchange as perpetually reusable. This is structurally similar to the sibling CVE-2026-5773 (SMB connection reuse) and CVE-2026-4873 (TLS requirement bypass on reuse) disclosed in the same coordinated batch, suggesting a systemic pattern in curl's connection-reuse logic across protocols.
