TDengine: Standard User permission unexpect
Summary
TDengine is an open source, time-series database optimized for Internet of Things devices. Prior to 3.4.1.15, a Data Reader admin_user on a TDengine Cloud DB instance could run create udf even though standard users should have read-only permissions for non-database objects and show dnodes and create user were denied. This issue is fixed in version 3.4.1.15.

TDengine: Authenticated Out-of-Bounds Read in SQL Lexer tGetToken
Summary
TDengine is a time-series database optimized for Internet of Things devices. Prior to 3.4.1.14, source/libs/parser/src/parTokenizer.c tGetToken() incremented past a trailing backslash in a SQL string literal such as 'abc\ and read one byte beyond the null terminator, allowing an authenticated user who can submit SQL queries to crash the server and possibly leak adjacent memory. This issue is fixed in version 3.4.1.14.

Title
TDengine: Unauthenticated Remote Denial of Service via Out-of-Bounds Read in transDecompressMsg
Summary
TDengine is a time-series database optimized for Internet of Things devices. Prior to 3.4.1.15, source/libs/transport/src/transComm.c transDecompressMsg() read STransCompMsg.contLen when pHead->comp == 1 without first validating that the RPC packet contained the 8-byte STransCompMsg structure, causing an unauthenticated out-of-bounds read, uncontrolled allocation, integer underflow, and server crash. This issue is fixed in version 3.4.1.15.

TDengine: UDF lead to RCE
Summary
TDengine is an open source, time-series database optimized for Internet of Things devices. Prior to 3.4.1.15, a user with create udf privilege could upload a crafted shared library and install it as a user-defined function, such as eval, then execute arbitrary C code on the TDengine server side through database queries. This issue is fixed in version 3.4.1.15.

Title
TDengine: Off-by-One Buffer Overflow
Summary
TDengine is an open source, time-series database optimized for Internet of Things devices. In 3.4.1.6 and earlier, source/libs/parser/src/parUtil.c trimString() checks space for only one byte before processing SQL string escape sequences \%, \_, or \x, allowing a one-byte out-of-bounds write to the stack buffer tmpTokenBuf that can cause denial of service and potentially remote code execution. This issue is fixed in version 3.4.1.14.

TDengine: KILL SSMIGRATE missing authorization lets low-privilege users interrupt shared-storage migrations
Summary
TDengine is a time-series database optimized for Internet of Things devices. Prior to 3.4.1.15, TDengine Enterprise allowed an authenticated low-privilege SQL user to run KILL SSMIGRATE <id> against an active shared-storage migration because mndProcessKillSsMigrateReq called mndKillSsMigrate while the intended MND_OPER_SSMIGRATE_DB privilege check was commented out. This issue is fixed in version 3.4.1.15.

Title
Command Injection Vulnerability in `Release PR Merged` Workflow in taosdata/grafanaplugin
Summary
The `Release PR Merged` workflow in the github repo taosdata/grafanaplugin is subject to a command injection vulnerability which allows for arbitrary code execution within the github action context due to the insecure usage of `${{ github.event.pull_request.title }}` in a bash command within the GitHub workflow. Attackers can inject malicious commands which will be executed by the workflow. This happens because `${{ github.event.pull_request.title }}` is directly passed to bash command on like 25 of the workflow. This may allow an attacker to gain access to secrets which the github action has access to or to otherwise make use of the compute resources.

Summary
TDengine is a time-series database optimized for Internet of Things devices. Prior to 3.4.1.14, source/libs/parser/src/parTokenizer.c tGetToken() incremented past a trailing backslash in a SQL string literal such as 'abc\ and read one byte beyond the null terminator, allowing an authenticated user who can submit SQL queries to crash the server and possibly leak adjacent memory. This issue is fixed in version 3.4.1.14.

TDengine: Unauthenticated Remote Denial of Service via Out-of-Bounds Read in transDecompressMsg
Summary
TDengine is a time-series database optimized for Internet of Things devices. Prior to 3.4.1.15, source/libs/transport/src/transComm.c transDecompressMsg() read STransCompMsg.contLen when pHead->comp == 1 without first validating that the RPC packet contained the 8-byte STransCompMsg structure, causing an unauthenticated out-of-bounds read, uncontrolled allocation, integer underflow, and server crash. This issue is fixed in version 3.4.1.15.

Summary
TDengine is a time-series database optimized for Internet of Things devices. Prior to 3.4.1.15, TDengine Enterprise allowed an authenticated low-privilege SQL user to run KILL SSMIGRATE <id> against an active shared-storage migration because mndProcessKillSsMigrateReq called mndKillSsMigrate while the intended MND_OPER_SSMIGRATE_DB privilege check was commented out. This issue is fixed in version 3.4.1.15.

TDengine is an open source, time-series database optimized for Internet of Things devices.

This issue is fixed in version 3.4.1.14.

Summary
TDengine is an open source, time-series database optimized for Internet of Things devices. Prior to 3.4.1.15, a user with create udf privilege could upload a crafted shared library and install it as a user-defined function, such as eval, then execute arbitrary C code on the TDengine server side through database queries. This issue is fixed in version 3.4.1.15.

Title
Command Injection Vulnerability in `Release PR Merged` Workflow in taosdata/grafanaplugin
Summary
The `Release PR Merged` workflow in the github repo taosdata/grafanaplugin is subject to a command injection vulnerability which allows for arbitrary code execution within the github action context due to the insecure usage of `${{ github.event.pull_request.title }}` in a bash command within the GitHub workflow. Attackers can inject malicious commands which will be executed by the workflow. This happens because `${{ github.event.pull_request.title }}` is directly passed to bash command on like 25 of the workflow. This may allow an attacker to gain access to secrets which the github action has access to or to otherwise make use of the compute resources.
