CVSS v3.1 |
| Root File System Not Mounted as Read-Only configuration vulnerability. This can allow unintended modifications to critical system files, potentially increasing the risk of system compromise or unauthorized changes.This issue affects AION: 2.0. |
| The nohup utility in uutils coreutils creates its default output file, nohup.out, without specifying explicit restricted permissions. This causes the file to inherit umask-based permissions, typically resulting in a world-readable file (0644). In multi-user environments, this allows any user on the system to read the captured stdout/stderr output of a command, potentially exposing sensitive information. This behavior diverges from GNU coreutils, which creates nohup.out with owner-only (0600) permissions. |
| A vulnerability in uutils coreutils mkfifo allows for the unauthorized modification of permissions on existing files. When mkfifo fails to create a FIFO because a file already exists at the target path, it fails to terminate the operation for that path and continues to execute a follow-up set_permissions call. This results in the existing file's permissions being changed to the default mode (often 644 after umask), potentially exposing sensitive files such as SSH private keys to other users on the system. |
| Pyroscope is an open-source continuous profiling database. The database supports various storage backends, including Tencent Cloud Object Storage (COS).
If the database is configured to use Tencent COS as the storage backend, an attacker could extract the secret_key configuration value from the Pyroscope API.
To exploit this vulnerability, an attacker needs direct access to the Pyroscope API. We highly recommend limiting the public internet exposure of all our databases, such that they are only accessible by trusted users or internal systems.
This vulnerability is fixed in versions:
1.15.x: 1.15.2 and above.
1.16.x: 1.16.1 and above.
1.17.x: 1.17.0 and above (i.e. all versions).

content: "# Cross-Tenant Legacy Correlation Disclosure and Deletion"
date: 2026-01-29
product: Grafana
severity: Low
cve: CVE-2026-21727
cvss_score: "3.3"
cvss_vector: "CVSS:3.3/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:L/A:N"
fixed_versions:

---
A cross-tenant isolation vulnerability was found in Grafana’s Correlations feature affecting legacy correlation records. Due to a backward compatibility condition allowing org_id = 0 records to be returned across organizations, a user with datasource management privileges could read and permanently delete legacy correlation data belonging to another organization. This issue affects correlations created prior to Grafana 10.2 and is fixed in >=11.6.11, >=12.0.9, >=12.1.6, and >=12.2.4.
Thanks to Gyu-hyeok Lee (g2h) for reporting this vulnerability. |
| The poll_mode_io file for the megaraid_sas driver in the Linux kernel 2.6.31.6 and earlier has world-writable permissions, which allows local users to change the I/O mode of the driver by modifying this file. |
| XTerm in Apple Mac OS X 10.4.11 and 10.5.6, when used with luit, creates tty devices with insecure world-writable permissions, which allows local users to write to the Xterm of another user. |
| IBM Lotus Notes before 6.5.6, and 7.x before 7.0.3; and Domino before 6.5.5 FP3, and 7.x before 7.0.2 FP1; uses weak permissions (Everyone:Full Control) for memory mapped files (shared memory) in IPC, which allows local users to obtain sensitive information, or inject Lotus Script or other character sequences into a session. |
| TrustPort Antivirus before 2.8.0.2266 and PC Security before 2.0.0.1291 use weak permissions (Everyone: Full Control) for files under %PROGRAMFILES%, which allows local users to gain privileges by replacing executables with Trojan horse programs. |
| common/snapshots.py in Back In Time (aka backintime) 0.9.26 changes certain permissions to 0777 before deleting the files in an old backup snapshot, which allows local users to obtain sensitive information by reading these files, or interfere with backup integrity by modifying files that are shared across snapshots. |
| nss-ldapd before 0.6.8 uses world-readable permissions for the /etc/nss-ldapd.conf file, which allows local users to obtain a cleartext password for the LDAP server by reading the bindpw field. |
| Red Hat Directory Server 8.0, when running on Red Hat Enterprise Linux, uses insecure permissions for the redhat-idm-console script, which allows local users to execute arbitrary code by modifying the script. |
| The g_file_copy function in glib 2.0 sets the permissions of a target file to the permissions of a symbolic link (777), which allows user-assisted local users to modify files of other users, as demonstrated by using Nautilus to modify the permissions of the user home directory. |
| The I2O Utility Filter driver (i2omgmt.sys) 5.1.2600.2180 for Microsoft Windows XP sets Everyone/Write permissions for the "\\.\I2OExc" device interface, which allows local users to gain privileges. NOTE: this issue can be leveraged to overwrite arbitrary memory and execute code via an IOCTL call with a crafted DeviceObject pointer. |
| Dovecot 1.2.x before 1.2.8 sets 0777 permissions during creation of certain directories at installation time, which allows local users to access arbitrary user accounts by replacing the auth socket, related to the parent directories of the base_dir directory, and possibly the base_dir directory itself. |
| The Replace function in the capp-lspp-config script in the (1) lspp-eal4-config-ibm and (2) capp-lspp-eal4-config-hp packages before 0.65-2 in Red Hat Enterprise Linux (RHEL) 5 uses lstat instead of stat to determine the /etc/pam.d/system-auth file permissions, leading to a change to world-writable permissions for the /etc/pam.d/system-auth-ac file, which allows local users to gain privileges by modifying this file. |
| Invensys Wonderware InTouch 8.0 creates a NetDDE share with insecure permissions (Everyone/Full Control), which allows remote authenticated attackers, and possibly anonymous users, to execute arbitrary programs. |
| mount.cifs in Samba 3.0 before 3.0.37, 3.2 before 3.2.15, 3.3 before 3.3.8 and 3.4 before 3.4.2, when mount.cifs is installed suid root, does not properly enforce permissions, which allows local users to read part of the credentials file and obtain the password by specifying the path to the credentials file and using the --verbose or -v option. |
| Adobe Photoshop Elements 8.0 installs the Adobe Active File Monitor V8 service with an insecure security descriptor, which allows local users to (1) stop the service via the stop command, (2) execute arbitrary commands as SYSTEM by using the config command to modify the binPath variable, or (3) restart the service via the start command. |
| Red Hat Directory Server 7.1 before SP4 uses insecure permissions for certain directories, which allows local users to modify JAR files and execute arbitrary code via unknown vectors. |
