Vulnerabilities

Scriban before 6.6.0 contains an uncontrolled recursion vulnerability in its recursive-descent parser.

Scriban before 6.6.0 contains an infinite recursion vulnerability in object rendering when the ObjectRecursionLimit property defaults to unlimited.

Scriban before 7.0.0 (affected versions <= 6.6.0) contains a stack overflow vulnerability in nested array initializer parsing.

Scriban before 7.0.0 fails to clear the CachedTemplates dictionary when TemplateContext.Reset() is called, allowing cached templates to persist across reused contexts.

Scriban before 7.0.0 caches TypedObjectAccessor by Type only without considering MemberFilter changes, allowing reused TemplateContext instances to expose members that should be hidden.

Scriban before 7.0.0 (affected <= 6.6.0) applies its LoopLimit constraint only to script loop statements and not to expensive iteration performed inside built-in operators and functions.

Scriban before 7.0.0 (affected versions <= 6.6.0) contains an uncontrolled memory allocation vulnerability in the string.pad_left and string.pad_right template functions, which perform no validation on the width paramete…

Scriban before 7.0.0 contains an uncontrolled recursion vulnerability in the object.to_json builtin function that lacks depth limits and circular reference detection.

Scriban before 7.0.0 (affected versions <= 6.6.0) contains a denial-of-service vulnerability in which the LimitToString safety limit (default 1MB) can be bypassed because ObjectToString resets the per-call length counter…

Scriban before 7.0.0 contains three distinct denial-of-service vulnerabilities in expression evaluation that bypass existing safety controls through unbounded string multiplication, uncontrolled BigInteger shift operatio…

Scriban before 7.2.0 contains a denial of service vulnerability in the array.insert_at function that allocates unbounded null entries without respecting LoopLimit or LimitToString constraints.

Scriban versions 6.6.0 through 7.2.0 contain a non-enforcing ExpressionDepthLimit guard that fails to stop recursive descent parsing of deeply nested expressions.

Scriban versions 3.0.0 through 7.2.0 contain a denial of service vulnerability in the array multiplication operator that allocates memory without enforcing LoopLimit or overflow-safe arithmetic checks.

Scriban before 7.2.2 contains an access-modifier bypass vulnerability in TypedObjectAccessor that allows template code to write CLR object properties without setter-visibility checks.

Scriban versions from 3.0.0 through 7.2.5 contain a denial of service vulnerability in the ScriptRange.Multiply operator that bypasses LoopLimit when the left operand is a lazy sequence.
