CVE-2026-49232
HighCVSS 8.7Exploitation Probability (EPSS)
Low risk27th percentile - higher than 27% of all known CVEs
Summary
Routinator exits on any error when accepting incoming HTTP or RTR connections, including recoverable ones like running out of file descriptors. An attacker can trigger this by opening many connections.
Risk Assessment
An attacker can cause a denial of service (DoS) by exhausting file descriptors, forcing Routinator to exit. This only affects users exposing the HTTP/RTR server to untrusted networks.
Recommendation
Restrict access to the HTTP/RTR server to trusted networks only, or apply a workaround if available.
Other vulnerabilities in Routinator
See all- CVE-2026-49235High
Vulnerability in Routinator causes a crash when encountering an RRDP file with a specially crafted Document Type Definition (DTD).
- CVE-2026-49234High
When sending a specifically crafted non-UTF-8 string as select-asn query parameter to the /api/v1/origins endpoint, Routinator crashes. This only affects users who allow API access from untrusted networks.
- CVE-2026-49233High
Routinator does not properly check the module component of rsync URIs, which are used to create the file system paths for the Routinator cache. This allows for path traversal by having a module name containing .., potentially providing an attacker access to the entire Routinator rsync cache.
Original NVD description (English source)
Routinator exits on any error when accepting incoming HTTP or RTR connections, including ones it can recover from such as running out of file descriptors. This condition can be triggered maliciously by an attacker by opening a large number of connections to the HTTP or RTR server. This only affects users that make their HTTP or RTR server available to untrusted networks.
