{"apiVersion":"1.0","identifier":"CVE-2026-26453","description":"ccoap 77f55c4b466e99327c24ace8a2913d3ba7e2ccd5 contains a null pointer dereference vulnerability in the coap_server_handle_session() function when processing COAP messages containing URI_PATH options with NULL data pointers. When the server searches for a URI_PATH option matching the string -separate-, it directly calls strncmp() on option_list[i].data without checking if the pointer is NULL. This causes a segmentation fault when the option-s data field is NULL.","publishedAt":"2026-08-27T17:17:48","lastModifiedAt":"2026-08-27T17:17:48","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-26453","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00155,"riskScore":0,"affectedProduct":"ccoap","affectedVersions":"cannotmatch","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-26453","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-26453","en":"https://www.redsauce.net/en/cves/CVE-2026-26453","fr":"https://www.redsauce.net/fr/cves/CVE-2026-26453","pt":"https://www.redsauce.net/pt/cves/CVE-2026-26453","de":"https://www.redsauce.net/de/cves/CVE-2026-26453","sk":"https://www.redsauce.net/sk/cves/CVE-2026-26453","el":"https://www.redsauce.net/el/cves/CVE-2026-26453"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-26453"}}
