Denial Of Service (DoS)
sqlparse is vulnerable to Denial of Service DoS. The vulnerability is due to repeated rescanning of comment-only SQL statements before the grouping limit is enforced, which allows an attacker to provide crafted input that causes quadratic CPU consumption and degrades application performance...
brace-expansion: Brace-expansion: Denial of Service due to exponential-time complexity
A flaw was found in brace-expansion. An attacker can exploit a vulnerability in the expand function by providing a specially crafted string. This string, containing consecutive non-expanding brace groups, can trigger exponential-time complexity, leading to significant CPU consumption and event-lo...
CVE-2026-59887
A flaw was found in linkify-it, a library for recognizing links. A remote attacker could exploit this vulnerability by providing specially crafted user text. The mailto: schema validator, when processing this input, can be repeatedly invoked, leading to excessive CPU consumption. This can result ...
BIT-MONGODB-2026-13074 Awaitable Hello Command in Exhaust Mode Unthrottled Response Loop Leading to Denial of Service
An unauthenticated remote client can cause excessive CPU consumption on a MongoDB server by sending a specific combination of parameters to the awaitable hello command in exhaust mode. The server's handling of this combination results in a response loop that bypasses normal throttling, allowing a...

CVE-2026-66046
Expat through 2.8.3 contains a denial of service vulnerability caused by quadratic algorithmic complexity in the storeAtts function in xmlparse.c, where processing N specified attributes with non-normalized values triggers an ON^2 linear scan of elementType-defaultAtts to determine CDATA status. ...
mime: golang: Golang MIME: Denial of Service via maliciously-crafted MIME header
A flaw was found in the Golang MIME Multipurpose Internet Mail Extensions package. A remote attacker could exploit this vulnerability by sending a maliciously-crafted MIME header containing many invalid encoded-words. This could lead to excessive CPU consumption, resulting in a Denial of Service...
Denial of Service (DoS)
Overview Affected versions of this package are vulnerable to Denial of Service DoS via the groupcomments function in sqlparse/engine/grouping.py when parsing a statement composed entirely of comment tokens e.g., repeated -- c\n lines. The function rescans the entire remaining token tail once per...
CVE-2026-59893
sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, SQLREGEX in sqlparse/keywords.py and the per-position loop in sqlparse/lexer.py repeatedly scan unmatched dollar-quoted literal and multiline-comment delimiters, causing quadratic CPU consumption through sqlparse.parse,...
CVE-2026-54284
sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, TokenList construction and string conversion in sqlparse/sql.py repeatedly flatten nested token subtrees constructed by groupparenthesis and groupcase, causing quadratic CPU consumption through sqlparse.parse,...

CVE-2026-71491 sqlparse: Quadratic O(n²) DoS in group_comments
sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, groupcomments in sqlparse/engine/grouping.py repeatedly rescans comment-only statements before the MAXGROUPINGTOKENS guard, causing quadratic CPU consumption through sqlparse.parse and sqlparse.formatsql, stripcomments=Tru...
BIT-MONGODB-2026-13064 MongoDB $jsonSchema Query Operator Excessive CPU Consumption Leading to Denial of Service
Certain query operations involving deeply nested $jsonSchema constructs can trigger disproportionate CPU consumption in affected MongoDB deployments, potentially leading to resource exhaustion. The resulting CPU-bound operation cannot be interrupted through standard administrative controls...

CVE-2026-71491: Uncontrolled Resource Consumption
sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, groupcomments in sqlparse/engine/grouping.py repeatedly rescans comment-only statements before the MAXGROUPINGTOKENS guard, causing quadratic CPU consumption through sqlparse.parse and sqlparse.formatsql, stripcomments=Tru...
CVE-2026-54284: Inefficient Algorithmic Complexity
