9.0.7

Valkey 9.0.7 - Released Mon 26 October 2026

Upgrade urgency SECURITY: This release includes security fixes we recommend you apply as soon as possible.

Security Fixes

• GHSA-f4q9-j22m-xqq9: Fix a heap buffer overflow in cluster Pub/Sub message construction that could allow an authenticated client to potentially execute arbitrary code by publishing an oversized message by @roshkhatri (#5030)

Bug Fixes

• Fix stream commands that mutate consumer-group or PEL state (XGROUP, XSETID, XREADGROUP, XACK, XCLAIM, XAUTOCLAIM) not triggering WATCH and client-side tracking invalidation by @Tarte12 (#3459)
• Reject module write commands while the server is paused for writes, preventing a crash from module timer callbacks during CLIENT PAUSE WRITE or CLUSTER FAILOVER by @smkher (#3645)
• Fix a server abort on a RESTORE payload declaring a string length that overflows the allocation size; such payloads are now rejected as bad data by @enjoy-binbin (#4733)
• Fix ZINTER/ZINTERSTORE returning input-order-dependent scores when a weighted term is 0*inf; a NaN weighted score now counts as 0, matching ZUNION by @leomurillo (#4997)
• Correct ValkeyModule_FreeModuleUser, ValkeyModule_ACLAddLogEntry and ValkeyModule_ACLAddLogEntryByUserName declarations to return int as implemented, fixing undefined behavior on targets with strict call signature checks by @rainsupreme (#4676)
• valkey-check-aof now recognizes RDB base files with the VALKEY signature instead of misreporting a valid multipart AOF as invalid by @sarthakaggarwal97 (#4739)
• Fix a huge memory allocation when a command such as COMMAND GETKEYS EVAL declares a far larger key count than the arguments provided by @murphyjacob4 (#3598)
• Reject relative expire times in SET/GETEX, RESTORE, and ValkeyModule_SetExpire that overflow when added to the current time, preventing server aborts from negative expires by @madolson (#4880)
• HDEL, HGETDEL, HPERSIST, and HEXPIRE no longer propagate fields they treat as expired, preventing replica and AOF-reload divergence by @xdk-amz (#4772)
• Fix a server crash when loading an ACL file containing a selector with an unmatched parenthesis by @magic-peach (#4214)
• COPY of a hash now includes expired-but-unreaped fields so their deletion is propagated and replicas stay in sync by @pirate329 (#4939)
• Sorted set range commands with a negative LIMIT offset now return an empty result instead of a spurious element on btree-encoded keys by @xiaocj (#4637)
• Fix atomic slot migration not replicating evictions on the import target, which let replicas grow far past maxmemory by @shanezx-sc (#4920)
• Redact error text in server logs when hide-user-data-from-log is enabled, so command arguments no longer leak into logs by @zackcam (#4815)
• Fix HSETEX and HGETEX failing to parse their arguments when the key is named fields by @sebxt (#4945)
• Fix cluster config saving to avoid publishing truncated nodes.conf files, losing the startup lock after the first save, and failing every save on SMB filesystems such as Azure Files; the lock now lives on a separate nodes.conf.lock file by @KewangZhili (#4489)
• Fix atomic slot migration with cluster-databases > 1 applying writes made during the snapshot to the wrong database on the target by @pirate329 (#4952)
• Fix LSET on 64-bit builds silently modifying the wrong element for out-of-range indexes instead of returning an index out of range error by @charsyam (#4823)
