CVE-2026-104432

Zebra versions prior to 6.3.0 are vulnerable to an improper exceptional condition check within the ChainSync::obtain_tips function. This flaw causes the software to discard valid one-hash FindBlocks responses, resulting in the node falsely reporting a close-to-tip status. When peers return only t...

CVE-2026-104431

Versions of Zebra prior to 6.0.0 are vulnerable to a denial of service (DoS) condition. The root cause is a vulnerability where unauthenticated peers can stall Tokio workers by submitting mempool transactions that require expensive synchronous script verification . Specifically, attackers can tra...

CVE-2026-104429

The Zebra (zebrad) software, versions 5.0.0 before 6.0.0-rc.0 , is vulnerable to a mempool admission bypass. The root cause is that the system fails to apply per-peer mempool admission caps to transactions received as direct P2P tx messages , as these are queued without recording the sending peer...

CVE-2026-104430

The software zebra zebrad 4.5.0 and zebra-script 7.0.0 contains a vulnerability where P2SH redeem script signature operations are counted in legacy mode instead of the accurate P2SH mode used by zcashd . This causes CHECKMULTISIG preceded by OP_1 through OP_16 to be overcounted as 20 sigops, lead...

CVE-2026-104428

The zebra-rpc component in the Zcash Foundation's Zebra node (versions before 11.0.0 ) is vulnerable to a Denial of Service (DoS) . The getblock RPC method panics when handling a side-chain block with verbosity 2 because a -1 confirmations sentinel is converted to u32 using .expect() , causing th...

CVE-2026-104427

Zebra versions before 6.1.0 are vulnerable to an incomplete cleanup vulnerability within the state write task . This flaw allows remote unauthenticated peers to stall node synchronization by poisoning the parent_error_map . Specifically, an attacker can deliver a coinbase-malleated block that sha...

CVE-2026-104426

Zebra versions before 6.1.0 are susceptible to an inefficient algorithmic complexity vulnerability (CWE-407) within the remaining_transaction_value function. The root cause is the cloning of the entire block-level spent-UTXO map for every transaction during contextual verification. This allows an...

CVE-2026-104425

ZcashFoundation Zebra versions before 6.1.0 are susceptible to a resource exhaustion vulnerability. Unauthenticated peers can degrade block processing by pushing transactions containing invalid Orchard proofs without being misbehavior-scored. By repeatedly pushing these invalid proofs into the sh...

CVE-2026-104423

The Zebra (zebrad) software, specifically versions before 6.2.1 , is susceptible to an asymmetric resource consumption vulnerability (CWE-405). This flaw allows unauthenticated peers to stall block verification by flooding the shared unprioritized Halo2 verification queue with zero-fee transactio...

CVE-2026-104424

Zebra versions prior to 6.1.0 are vulnerable to an incorrect calculation in the ZIP-317 block template selector . The flaw stems from omitting the header and transaction-count size from the block budget. An attacker can exploit this by placing valid selectable transactions into a victim miner's m...

CVE-2026-104422

Zebra (zebrad) versions before 6.3.0 are vulnerable to a Denial of Service (DoS) attack in the block sync download path. The software reads a block's height from an unvalidated coinbase scriptSig and drops blocks that appear too far behind the tip before consensus validation occurs, without penal...

CVE-2026-104421

Zebra versions before 6.2.1 are vulnerable to an incomplete cleanup vulnerability (CWE-459). This flaw allows unauthenticated peers to prevent the downloading of valid blocks by leaving rejected hashes in SentHashes . An attacker can transmit a contextually invalid block that shares an honest blo...

CVE-2026-104419

The Zebra (zebrad) software, versions 4.5.0 before 6.3.0 , is vulnerable to a logic flaw in how it handles FindBlocks responses. The software fails to track which peer provided specific block hashes, leading it to assign 100 misbehavior points (the ban threshold) to any peer that serves a block m...

CVE-2026-104420

The Zebra software (versions before 6.3.0 ) contains a protection mechanism failure that allows unauthenticated peers to evade misbehavior scoring. The vulnerability occurs during an inbound cleanup step where the system wrongly downcasts RouterError to VerifyBlockError , causing the associated s...

CVE-2026-104418

Ghost versions 6.10.3 before 6.64.0 are vulnerable to remote code execution (RCE) due to an abuse of the theme translation file loading mechanism. Authenticated administrators can exploit this by uploading a crafted theme containing malicious translation files to execute arbitrary code on the Gho...

CVE-2026-104416

Ghost versions 4.39.0 through 6.64.0 are vulnerable to an information disclosure vulnerability within the Admin API . This flaw allows staff users with invite viewing permissions to access secret tokens for pending staff invites. By obtaining these tokens, an attacker can accept invites for highe...

CVE-2026-104417

The Ghost platform (versions 1.20.0 before 6.64.0 ) is vulnerable to a path traversal flaw in the theme translation file loading mechanism. This issue allows authenticated administrators to manipulate the locale setting to load JSON files from locations outside the active theme directory. Success...

CVE-2026-104415

The Ghost platform (versions 0.7.2 before 6.64.0 ) contains an information disclosure vulnerability within the Admin API . Authenticated users with staff-level privileges can query the Admin API to determine the relative ordering of password hashes belonging to other staff users. While this allow...

CVE-2026-104414

Ghost versions 2.5.0 before 6.64.0 are susceptible to a stored cross-site scripting (XSS) vulnerability. The root cause is the processing of untrusted scripts through oEmbed photo responses . An attacker can host malicious oEmbed responses which, when embedded, execute scripts in the Ghost editor...

CVE-2026-104413

Ghost versions 5.94.0 before 6.64.0 are vulnerable to a stored cross-site scripting (XSS) vulnerability. This flaw occurs when the application allows staff users, including Contributors, to host arbitrary HTML by abusing the bookmark card image fetching mechanism. An attacker can create bookmark ...
