Authenticated environment disclosure and memory exhaustion via eval
Published Sep 7, 2026 · Updated Sep 8, 2026
FreeIPA idp-add eval injection in Red Hat Enterprise Linux 8, 9, and 10 allows remote authenticated users to read environment data. The --organization and --base-url values reach a parenthesis-blocked eval() before the LDAP access-control check, enabling dictionary unpacking, exception oracles, and exponentiation. Any authenticated IPA principal can trigger the path; standard RPM deployments expose nonsensitive process values, retained container password variables expose credentials, and crafted exponentiation exhausts memory.
