Description
This security bulletin contains information about 3 vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2026-73507)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources in XmlFrameDecoder. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Always-Incorrect Control Flow Implementation (CVE-ID: CVE-2026-53404)
CWE-ID: CWE-670 - Always-Incorrect Control Flow Implementation
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to bypass rewrite conditions.
The vulnerability exists due to logic errors in RewriteValve when processing requests against OR-chained rewrite conditions. A remote attacker can send a request that matches the first OR condition to bypass rewrite conditions.
Exploitation requires a rule set that uses an OR chain followed by non-OR conditions.
3) Integer overflow (CVE-ID: CVE-2026-73086)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 9.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to predict generated identifiers and bypass authentication.
The vulnerability exists due to integer overflow or wraparound in the nanoid(size) function when processing a user-controlled size parameter. A remote attacker can submit a size value of at least 2^31 to corrupt the process-wide CSPRNG pool and predict subsequently generated tokens.
The issue affects all consumers of nanoid in the same process until the process restarts or the pool offset wraps back to a positive value.
