The getblock RPC method in zebra-rpc before 11.0.0, used by the Zcash Foundation's Zebra node, panics on verbosity 2 for a side-chain block because the block's -1 confirmations sentinel is converted to u32 with .expect(), aborting the process. Remote unauthenticated attackers, directly or through lightwalletd, can repeat this call to keep the node in a crash loop.

——9As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco Expressway Series software engineering team has conducted a comprehensive internal security review. This review resulted in software hardening releases that address multiple internally discovered vulnerabilities.
The vulnerabilities tracked by CVE-2026-76491 are related to issues concerning reachable assertions that are grouped under the Common Weakness Enumeration (CWE) Base CWE-617.3dCVE-2026-1024837.5 ALT36.8%
——11Reachable exit in NTPsec ntpd 1.1.4 through 1.2.5 allows a remote attacker to terminate the daemon via an NTS request with excess NTS Cookie Placeholder extension fields.4dCVE-2026-973137.5 ALT38.7%
——12A recursive BIND server that receives a query with recursion desired (RD=1) followed by a non-recursive query (RD=0) may exit with an assertion failure, resulting in a denial of service. To be vulnerable, the BIND server must allow recursive queries and have at least two RPZ zones configured: one with the default setting of "recursive-only yes", and the other with "recursive-only no".
This issue affects BIND 9 versions 9.16.0 through 9.18.50, 9.20.0 through 9.20.29, 9.21.0 through 9.21.26, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.29-S1.4dCVE-2026-968887.5 ALT39.7%
——12A BIND resolver that is configured with both a "redirect" zone and "qname-minimization strict" may abort with an assertion failure while processing the redirect.
This issue affects BIND 9 versions 9.16.0 through 9.18.50, 9.20.0 through 9.20.29, 9.21.0 through 9.21.26, 9.16.8-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.29-S1.4dCVE-2026-98253.7 BAJ15.5%
——5IBM Cyber Fraud 1.0.0 through 1.0.2 has a missing secure attribute allowing sensitive cookies to be transmitted over unencrypted connections, potentially enabling an attacker to intercept session data through network-based attacks.4dCVE-2026-43853—33.5%
——10A vulnerability could allow an attacker to send a crafted message to trigger an assertion fault, causing the service to crash.5d
