BIT-GHOST-2026-53946 Ghost: Mobiledoc image-size fetch SSRF

Ghost is a Node.js content management system. From 6.19.4 until 6.21.1, when re-rendering posts, Ghost would refetch missing image dimensions by issuing an outbound HTTP request to the URL stored on an image card — without restricting that URL to trusted image hosts. An authenticated staff user...

DEBIAN-CVE-2026-56365

ImageMagick before 7.1.2-19 contains a memory leak vulnerability in the PNG encoder when writing MNG images. Attackers can trigger the encoder failure condition to exhaust memory resources and cause denial of service...

DEBIAN-CVE-2026-56377

ImageMagick before 7.1.2-24 contains an incorrect policy check that allows attackers to create or truncate files disallowed by security policies. Remote attackers can bypass path policy restrictions in sandboxed conversion services to write arbitrary files outside intended boundaries...

CVE-2026-56369

ImageMagick before 7.1.2-22 contains an information disclosure vulnerability in the PasskeyEncipherImage method due to AES-CTR nonce reuse. Attackers can exploit nonce reuse in the cipher implementation to recover plaintext information from encrypted images...

CVE-2026-56361

ImageMagick before 7.1.2-19 contains an off-by-one error in morphology validation allowing out-of-bounds heap buffer reads. Attackers can trigger heap buffer overflow by providing incorrect morphology parameters causing single pixel memory access violations...
