DescriptionNVD

Applications that build a Content-Disposition header value from untrusted input may be vulnerable to HTTP response splitting when the input is a malicious file name. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 - 6.2.19 Spring Framework 6.1.0 - 6.1.28 Spring Framework 6.0.0 - 6.0.30 Spring Framework 5.3.0 - 5.3.49 Spring Framework 5.2.25.RELEASE and earlier

AnalysisAI

HTTP response splitting in Spring Framework affects applications that construct Content-Disposition HTTP headers by concatenating untrusted user-supplied file names without stripping CRLF characters, allowing remote attackers to inject arbitrary headers into HTTP responses. The vulnerability spans the entire actively-maintained Spring Framework lineage - versions 5.2.x through 7.0.8 - giving it a broad potential surface across Java enterprise application portfolios. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the target application constructs an HTTP Content-Disposition header by incorporating a value derived from an untrusted external source - specifically a user-supplied request parameter, URL path segment, or externally-sourced file name - without sanitizing CRLF characters before header construction. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 base score of 3.7 (Low) with vector AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N accurately reflects the constrained real-world exploitability: the attack is network-reachable with no authentication required, but AC:H is well-justified because exploitation is contingent on a specific application-level code pattern - the application must expose a file download or content delivery endpoint and construct the Content-Disposition header by directly embedding attacker-controlled input without CRLF sanitization. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation The primary remediation is upgrading to a patched Spring Framework release; consult the vendor advisory at https://spring.io/security/cve-2026-59314 for confirmed fixed version numbers, as exact patch releases are not independently confirmed in the available intelligence data and should be verified before communicating upgrade targets to development teams. … Detailed patch versions, workarounds, and compensating controls in full report.
