CVE-2025-26413
Published: 22 April 2025
Summary
CVE-2025-26413 is a high-severity Improper Input Validation (CWE-20) vulnerability in Apache Kvrocks. Its CVSS base score is 7.5 (High).
Operationally, ranked in the top 32.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
CVE-2025-26413 is an improper input validation flaw in Apache Kvrocks that affects the SETRANGE command. The command fails to verify that the supplied offset value is a positive integer before using it as a string index, allowing an out-of-range access that terminates the server process. The issue is present in all versions through 2.11.1 and carries a CVSS 3.1 score of 7.5 with network attack vector and high availability impact.
An unauthenticated remote attacker can send a crafted SETRANGE request containing a negative or excessively large offset. Because the command requires no authentication or special privileges, the attacker can repeatedly trigger the crash to produce a denial-of-service condition against any reachable Kvrocks instance.
Apache’s advisory and the coordinated oss-security notice both state that the sole recommended mitigation is to upgrade to version 2.12.0, which contains the corrected input validation logic. No work-arounds are documented.
EPSS for the CVE rose from a low baseline to a recorded peak of 0.0115, indicating measurable post-disclosure exploitation interest before settling at the current value of 0.0052.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Security testing and developer training directly verify and enforce proper input validation, reducing exploitability of injection and malformed-data weaknesses.
Security testing and evaluation at multiple SDLC stages directly detects missing or flawed input validation, with the required remediation process ensuring fixes are applied.
Directly implements checks on information inputs to reject invalid data before processing.
Spam protection mechanisms perform filtering and detection on inbound/outbound messages, directly compensating for missing or weak input validation of unsolicited content.
