CVE-2026-18536
7.5 · HIGHOverview
CVE-2026-18536 is a high-severity vulnerability affecting rrwo data\. It was published on August 1, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
Data::Entropy versions before 0.010 for Perl read remote entropy sources over plain HTTP.
The Data::Entropy::RawSource::RandomOrg and Data::Entropy::RawSource::RandomnumbersInfo remote sources are accessed over plain HTTP.
The Data::Entropy::RawSource::RandomOrg integrity check trivially matches any non-empty byte string.
Any on-path attacker, such as open WiFi, a compromised ISP, captive portal, or a hostile egress proxy substitutes the response and thereby chooses the bytes returned by rand_bits and rand_int for every application that selected one of these sources via with_entropy_source. The _checkbuf method response is equally attacker-controlled, so the retry/sleep behaviour is steerable too.
Remediation
Check the references section for vendor advisories and patches from rrwo. Update data\ to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
