This page consolidates all known Common Vulnerabilities and Exposures (CVEs) associated with gluster. We track both calendar-based metrics (using fixed periods) and rolling metrics (using gliding windows) to give you a comprehensive view of security trends and risk evolution. Use these insights to assess risk and plan your patching strategy.
For a broader perspective on cybersecurity threats, explore the comprehensive list of CVEs by vendor and product. Stay updated on critical vulnerabilities affecting major software and hardware providers.
Total gluster CVEs: 21
Earliest CVE date: 18 Nov 2012, 23:55 UTC
Latest CVE date: 21 Feb 2023, 02:15 UTC
Latest CVE reference: CVE-2023-26253
30-day Count (Rolling): 0
365-day Count (Rolling): 0
Calendar-based Variation
Calendar-based Variation compares a fixed calendar period (e.g., this month versus the same month last year), while Rolling Growth Rate uses a continuous window (e.g., last 30 days versus the previous 30 days) to capture trends independent of calendar boundaries.
Month Variation (Calendar): 0%
Year Variation (Calendar): 0%
Month Growth Rate (30-day Rolling): 0.0%
Year Growth Rate (365-day Rolling): 0.0%
Average CVSS: 4.72
Max CVSS: 7.5
Critical CVEs (≥9): 0

These are the five CVEs with the highest CVSS scores for gluster, sorted by severity first and recency.
In Gluster GlusterFS 11.0, there is an xlators/mount/fuse/src/fuse-bridge.c notify stack-based buffer over-read.
In Gluster GlusterFS 11.0, there is an xlators/cluster/dht/src/dht-common.c dht_setxattr_mds_cbk use-after-free.
A flaw was found in glusterfs server through versions 4.1.4 and 3.1.2 which allowed repeated usage of GF_META_LOCK_KEY xattr. A remote, authenticated attacker could use this flaw to create multiple locks for single inode by using setxattr repetitively resulting in memory exhaustion of glusterfs server node.
It was found that the fix for CVE-2018-10927, CVE-2018-10928, CVE-2018-10929, CVE-2018-10930, and CVE-2018-10926 was incomplete. A remote, authenticated attacker could use one of these flaws to execute arbitrary code, create arbitrary files, or cause denial of service on glusterfs server nodes via symlinks to relative paths.
It was found that usage of snprintf function in feature/locks translator of glusterfs server 3.8.4, as shipped with Red Hat Gluster Storage, was vulnerable to a format string attack. A remote, authenticated attacker could use this flaw to cause remote denial of service.
A flaw was found in RPC request using gfs3_rename_req in glusterfs server. An authenticated attacker could use this flaw to write to a destination outside the gluster volume.
A flaw was found in RPC request using gfs2_create_req in glusterfs server. An authenticated attacker could use this flaw to create arbitrary files and execute arbitrary code on glusterfs server nodes.
A flaw was found in RPC request using gfs3_symlink_req in glusterfs server which allows symlink destinations to point to file paths outside of the gluster volume. An authenticated attacker could use this flaw to create arbitrary symlinks pointing anywhere on the server and execute arbitrary code on glusterfs server nodes.
A flaw was found in RPC request using gfs3_lookup_req in glusterfs server. An authenticated attacker could use this flaw to leak information and execute remote denial of service by crashing gluster brick process.
A flaw was found in RPC request using gfs3_mknod_req supported by glusterfs server. An authenticated attacker could use this flaw to write files to an arbitrary location via path traversal and execute arbitrary code on a glusterfs server node.
It was discovered that fsync(2) system call in glusterfs client code leaks memory. An authenticated attacker could use this flaw to launch a denial of service attack by making gluster clients consume memory of the host machine.
It was found that the "mknod" call derived from mknod(2) can create files pointing to devices on a glusterfs server node. An authenticated attacker could use this to create an arbitrary device and read data from any device attached to the glusterfs server node.
It was found that an attacker could issue a xattr request via glusterfs FUSE to cause gluster brick process to crash which will result in a remote denial of service. If gluster multiplexing is enabled this will result in a crash of multiple bricks and gluster volumes.
An information disclosure vulnerability was discovered in glusterfs server. An attacker could issue a xattr request via glusterfs FUSE to determine the existence of any file.
A flaw was found in the way dic_unserialize function of glusterfs does not handle negative key length values. An attacker could use this flaw to read memory from other locations into the stored dict value.
It was found that glusterfs server is vulnerable to multiple stack based buffer overflows due to functions in server-rpc-fopc.c allocating fixed size buffers using 'alloca(3)'. An authenticated attacker could exploit this by mounting a gluster volume and sending a string longer that the fixed buffer size to cause crash or potential code execution.
It was found that glusterfs server does not properly sanitize file paths in the "trusted.io-stats-dump" extended attribute which is used by the "debug/io-stats" translator. Attacker can use this flaw to create files and execute arbitrary code. To exploit this attacker would require sufficient access to modify the extended attributes of files on a gluster volume.
glusterfs is vulnerable to privilege escalation on gluster server nodes. An authenticated gluster client via TLS could use gluster cli with --remote-host command to add it self to trusted storage pool and perform privileged gluster operations like adding other machines to trusted storage pool, start, stop, and delete volumes.
glusterfs server before versions 3.10.12, 4.0.2 is vulnerable when using 'auth.allow' option which allows any unauthenticated gluster client to connect from any network to mount gluster storage volumes. NOTE: this vulnerability exists because of a CVE-2018-1088 regression.
A flaw was found in GlusterFS in versions prior to 3.10. A null pointer dereference in send_brick_req function in glusterfsd/src/gf_attach.c may be used to cause denial of service.
The __socket_proto_state_machine function in GlusterFS 3.5 allows remote attackers to cause a denial of service (infinite loop) via a "00000000" fragment header.
The GlusterFS functionality in Red Hat Storage Management Console 2.0, Native Client, and Server 2.0 allows local users to overwrite arbitrary files via a symlink attack on multiple temporary files created by (1) tests/volume.rc, (2) extras/hook-scripts/S30samba-stop.sh, and possibly other vectors, different vulnerabilities than CVE-2012-4417.
GlusterFS 3.3.0, as used in Red Hat Storage server 2.0, allows local users to overwrite arbitrary files via a symlink attack on temporary files with predictable names.
