CVE-2026-41040: Inefficient regular expression complexity in GROWI, Inc. GROWI
GROWI, Inc. 's GROWI product version 7. 5. 0 and earlier contains a vulnerability due to inefficient regular expression complexity, which can be exploited via crafted input strings to cause a denial of service. This vulnerability is classified as a regular expression denial of service (ReDoS). The CVSS v3. 0 score is 7. 5, indicating a high severity impact primarily affecting availability. There is no information about an official patch or remediation level from the vendor, and no known exploits are reported in the wild. The vulnerability requires no privileges and no user interaction to exploit over the network.
AI Analysis
Technical Summary
CVE-2026-41040 is a high severity vulnerability in GROWI, Inc.'s GROWI product (version 7.5.0 and earlier) caused by inefficient regular expression complexity. This flaw allows an attacker to craft input strings that trigger excessive processing time in regular expression evaluation, resulting in a denial of service condition. The vulnerability can be exploited remotely without authentication or user interaction, impacting the availability of the affected system. No official patch or remediation guidance is currently available from the vendor, and no exploits have been observed in the wild.
Potential Impact
Successful exploitation of this vulnerability results in denial of service (DoS) by causing the application to consume excessive CPU resources when processing crafted input strings. This impacts system availability but does not affect confidentiality or integrity. The vulnerability can be triggered remotely without authentication or user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict or sanitize untrusted input that may be processed by regular expressions in GROWI. Monitor vendor channels for updates and apply patches promptly once released.
